{"title":"Stainless Steel Welding Rods","description":"\u003cp\u003eStainless steel welding rods are austenitic SMAW electrodes designed to weld or join stainless steel base metals while preserving corrosion resistance and mechanical properties in the finished weld deposit. Selecting the wrong grade can introduce sensitization, carbide precipitation, or inadequate corrosion protection — which is why matching the electrode classification to your specific alloy and service environment matters as much as technique.

Use stringer beads rather than wide weaves, maintain interpass temperatures below 350°F for standard austenitic grades, and allow natural cooling between passes. These practices minimize heat-affected zone width and help preserve the chromium-oxide passive layer responsible for stainless corrosion resistance. Proper fit-up and back-purging on open-root pipe joints further reduce root-side oxidation.\u003c\/p\u003e","products":[{"product_id":"lincoln-ed033854-lincoln-er308-308l-n-tig-gtaw-welding-rod-3-32-in-3-10-lb-tube","title":"Lincoln ED033854 Lincoln ER308\/308L N TIG GTAW Welding Rod, 3\/32 in, 3 10 lb Tube","description":"\u003ch2\u003eLincoln Electric — Lincoln ED033854 Lincoln ER308\/308L N TIG GTAW Welding Rod, 3\/32 in, 3 10 lb Tube\u003c\/h2\u003e\n\u003cp\u003e“N” Designator - cobalt restriction of 0.05% max.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCONFORMANCES:\u003c\/strong\u003e SPECIFICATION, CLASSIFICATION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAWS:\u003c\/strong\u003e AWS A5.9, ER308, ER308L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification:\u003c\/strong\u003e Shielding Gas, Polarity, Elongation, %, Tensile Strength, MPa (ksi), Yield Strength @ 0.2% Offset, MPa (ksi)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTypical Result:\u003c\/strong\u003e 100% Ar, DC-, 46, 590 (86), 430 (62)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification:\u003c\/strong\u003e %Co, %C, %Cr, %Cu, %Mn, %Mo, %N, %Nb, %Ni, %P, %S, %Si, Ferrite Number (Delong ©), Ferrite Number (WRC-1992 ©)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eER308 Requirement:\u003c\/strong\u003e 0.08 max., 19.5 - 22.0, 0.75 max., 1.0 - 2.5, 0.75 max., Info.

The combination of the fine .030 in diameter and ER316L's molybdenum-enhanced chemistry makes this rod uniquely suited for thin-wall 316L tubing (0.028–0.065 in), instrument fittings, hygienic tri-clamp assemblies, and ultra-high-purity semiconductor or pharmaceutical piping systems where both dimensional precision and pitting resistance at chloride-exposed welds are mandatory.

Available in a .030 in (0.76 mm) diameter, 36-inch cut-length format packed in a 10 lb box, this rod is engineered for gas tungsten arc welding (GTAW) of 304, 304L, 308, and 308L base metals — the most widely used stainless steel grades in food processing, pharmaceutical, chemical, and architectural fabrication. The \"L\" (low-carbon) designation limits carbon content to ≤0.03%, which suppresses carbide precipitation at the heat-affected zone and greatly reduces susceptibility to intergranular corrosion and sensitization. Harris Products Group, a Lincoln Electric company, manufactures this rod under strict lot-release testing, providing certified mechanical properties and composition per heat number traceable back to the melt.\u003c\/p\u003e\n\u003cp\u003eThe .030 in diameter is the ideal choice for welding thin-gauge stainless sheet (16–22 gauge), tube, and pipe wall thicknesses down to 0.028 in. Precision TIG work on instrument tubing, hygienic fittings, brewery and dairy equipment, and architectural trim relies on the tight dimensional tolerances and low impurity levels that Harris achieves through controlled wire drawing. The 308L TIG rod is compatible with 100% argon shielding gas (the standard for stainless TIG) as well as argon-helium blends used to increase heat input on thicker sections without sacrificing arc control.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications \u0026amp; AWS Classification — ER308L\u003c\/h2\u003e\n\u003ctable class=\"pdp-spec-table\"\u003e\n  \u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eAWS Classification\u003c\/td\u003e\n\u003ctd\u003eER308L (AWS A5.9\/A5.9M)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eHarris Part Number\u003c\/td\u003e\n\u003ctd\u003e308LTE0\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e.030 in (0.76 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCut Length\u003c\/td\u003e\n\u003ctd\u003e36 in (914 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePackage Weight\u003c\/td\u003e\n\u003ctd\u003e10 lb box\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCarbon Content (max)\u003c\/td\u003e\n\u003ctd\u003e0.03% (low-carbon \"L\" grade)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eChromium Content\u003c\/td\u003e\n\u003ctd\u003e19.5–22.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eNickel Content\u003c\/td\u003e\n\u003ctd\u003e9.0–11.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eManganese\u003c\/td\u003e\n\u003ctd\u003e1.0–2.5%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSilicon\u003c\/td\u003e\n\u003ctd\u003e0.30–0.65%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePhosphorus (max)\u003c\/td\u003e\n\u003ctd\u003e0.03%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSulfur (max)\u003c\/td\u003e\n\u003ctd\u003e0.03%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eTensile Strength (as welded)\u003c\/td\u003e\n\u003ctd\u003e≥80,000 psi (551 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eYield Strength (as welded)\u003c\/td\u003e\n\u003ctd\u003e≥57,000 psi (393 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eElongation (as welded)\u003c\/td\u003e\n\u003ctd\u003e≥35%\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eDCEN (Direct Current Electrode Negative)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eShielding Gas\u003c\/td\u003e\n\u003ctd\u003e100% Argon or Ar\/He blends\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eProcess\u003c\/td\u003e\n\u003ctd\u003eGTAW (TIG)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBase Metals\u003c\/td\u003e\n\u003ctd\u003e304, 304L, 308, 308L, 321, 347 stainless steels\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA (Harris Products Group)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eBest Applications for ER308L TIG Welding Rod\u003c\/h2\u003e\n\u003cp\u003eThe Harris 308L stainless TIG rod excels across industries where corrosion resistance, cleanliness, and structural integrity in a single-pass or multi-pass weld are non-negotiable:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFood, Beverage \u0026amp; Dairy Equipment:\u003c\/strong\u003e Sanitary piping, pressure vessels, mixing tanks, CIP (clean-in-place) circuits, and heat exchangers fabricated from 304L or 316L stainless are routinely welded with ER308L.

Set high-frequency start or lift-arc start. For .030 in wire with thin-gauge sheet, begin at 40–80 amps; for 1\/8 in material, you may push to 120–150 amps. Use a foot pedal or hand amperage control where possible — stainless has low thermal conductivity and heat builds quickly. Pulse TIG (e.g., 100 Hz, 30% background, 30% on-time) dramatically improves thin-sheet weld quality by reducing heat input and distortion.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTungsten:\u003c\/strong\u003e Use a 3\/32 in or 1\/8 in diameter 2% ceriated or 2% lanthanated tungsten electrode (gold or black band). For .030 in filler on thin material, a sharpened 1\/16 in tungsten also works well.

ER308L limits carbon to ≤0.03% versus ≤0.08% in standard ER308. The low carbon content of ER308L prevents sensitization — the precipitation of chromium carbides at grain boundaries that reduces corrosion resistance. For any application where the finished weld will be exposed to corrosive environments or cannot be post-weld annealed, ER308L is strongly preferred over ER308.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can I use ER308L rod to weld 304L stainless steel?\u003c\/strong\u003e\u003cbr\u003eYes. ER308L is the standard filler metal for welding 304L (low-carbon 304) stainless. The matching chemistry and low-carbon specification make it the correct choice for 304L pipe, sheet, tube, and plate in all service conditions including chemical, food-grade, and pharmaceutical environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Why should I use 100% argon with 308L TIG rod?\u003c\/strong\u003e\u003cbr\u003eArgon provides the dense, protective shielding atmosphere stainless TIG welding requires. Carbon dioxide or CO₂-containing mixed gases (used in MIG welding) add carbon to the weld deposit, defeating the purpose of using low-carbon 308L filler. For stainless TIG, always use 100% argon or argon\/helium blends — never argon\/CO₂ or 75\/25 C25.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What is the correct tungsten for stainless TIG welding?\u003c\/strong\u003e\u003cbr\u003eUse 2% ceriated (grey band) or 2% lanthanated (gold\/black band) tungsten for DC stainless TIG welding. These tungsten types provide excellent arc starts and long electrode life on DC current. Do not use pure tungsten (green band) on DC — it is designed for AC aluminum welding.

The \"309\" designation indicates a higher alloy content than standard 308\/308L rod — specifically, 23–25% chromium and 12–14% nickel versus 308's 20% Cr \/ 10% Ni. This elevated alloy level serves two primary purposes: (1) it makes ER309L the standard choice for welding dissimilar metal joints between austenitic stainless steel and carbon or low-alloy steel, where the higher chromium dilutes less to a problematic composition when carbon steel contamination enters the weld pool; and (2) it provides excellent corrosion resistance for welding 309 and 309S base metals used in high-temperature furnace and heat-treating equipment.\u003c\/p\u003e\n\u003cp\u003eThe \"L\" suffix limits carbon to 0.03% maximum, reducing sensitization risk in the weld deposit and the heat-affected zone.

Use stringer passes rather than wide weave passes to further limit dilution per pass. After completing the root pass with ER309L, subsequent passes (if any) can use ER309L throughout for full dissimilar joints, or transition to ER316L if the stainless side is 316\/316L and the application requires it.\u003c\/p\u003e\n\n\u003ch2\u003eStorage and Handling of Harris ER309L TIG Rod\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eStore in original packaging in a dry, temperature-stable environment.

ER308L starts with ~20% Cr; after 30–40% carbon steel dilution, the deposit can drop below the 12% Cr threshold required for corrosion resistance. ER309L starts with 23–25% Cr, providing a dilution buffer that keeps the final deposit above minimum corrosion-resistance chemistry even with significant carbon steel pickup. AWS D1.6 and Lincoln\/Harris dissimilar filler selection guides recommend ER309L as the standard choice for carbon-to-stainless joints.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can ER309L be used to weld 304 to 304 (same-material joints)?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes — ER309L is an acceptable overmatch for 304\/304L same-material joints. The higher alloy content (extra Cr and Ni) versus ER308L provides slightly better corrosion resistance but also higher ferrite content, which can affect impact toughness at sub-zero temperatures. For pure same-material 304\/304L work, ER308L is the standard recommendation.

This pre-deposits ER309L weld metal on the carbon steel, so when the joint weld is made, the \"carbon steel\" side of the joint is actually ER309L — reducing dilution effects on the final joint weld. Buttering is required by many pressure vessel codes when welding P1 carbon steel to austenitic stainless in critical service.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Does ER309L work on 17-4 PH (precipitation-hardened) stainless steel?\u003c\/strong\u003e\u003cbr\u003e\nA: No — 17-4 PH is a martensitic precipitation-hardened stainless requiring specialized filler (ER630 \/ Harris 174PH-type product) to produce matching mechanical properties after the aging heat treatment. Using ER309L on 17-4 PH creates a compositionally mismatched austenitic deposit that will not respond to the aging cycle and may have inadequate strength for the application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What is the maximum service temperature for ER309L weld deposits?\u003c\/strong\u003e\u003cbr\u003e\nA: ER309L weld metal is suitable for service up to approximately 1,500–1,600 °F (816–871 °C) before sigma-phase embrittlement and carburization become concerns. For continuous service above 1,600 °F, use ER310 (25Cr-20Ni) which offers higher oxidation resistance.

Per AWS D1.1 Table 3.2 and Lincoln Electric preheat guidelines: ASTM A36 carbon steel under 3\/4 in thickness typically requires no preheat; 3\/4 in–1-1\/2 in requires 150 °F (66 °C); thicker sections require 200–300 °F (93–149 °C).

ER316L contains 2–3% Mo, which raises the pitting resistance equivalent (PRE = %Cr + 3.3×%Mo + 16×%N) significantly versus ER308L which has no molybdenum. Chloride ions in seawater aggressively pit and crevice-corrode welds that lack sufficient molybdenum content. Marine hardware, boat fittings, and offshore structural components in 316L stainless should always be welded with matching ER316L — using ER308L in these applications produces weld zones with lower pitting resistance than the base metal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can I use ER316L on 304 stainless?\u003c\/strong\u003e\u003cbr\u003eYes, ER316L can be used on 304 or 304L base metal and is considered an over-alloyed approach. The additional molybdenum provides extra corrosion resistance margin, which is beneficial in borderline chloride environments. The cost premium of ER316L over ER308L is the main consideration; for standard 304 applications in non-chloride service, ER308L is more economical and equally adequate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What is ferrite number (FN) and why does it matter for 316L welds?\u003c\/strong\u003e\u003cbr\u003eFerrite Number (FN) is a measure of the small amount of ferrite microstructure present in an otherwise fully austenitic weld deposit.

Adequate ferrite prevents solidification hot cracking — a defect mode in fully austenitic welds where the last liquid in the weld pool solidifies under tensile stress. Harris ER316L is formulated to deposit in the correct FN range.

With weld metal carbon content ≤ 0.04 % and a balanced 19–21 Cr \/ 9–11 Ni chemistry, Excalibur 308L prevents sensitization-induced intergranular corrosion while delivering smooth AC and DCEP arc performance in all positions.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is the Lincoln Excalibur 308L Stainless Welding Rod?\u003c\/h2\u003e\n\u003cp\u003eExcalibur 308L is Lincoln Electric's premium E308L-16 SMAW electrode for Type 304 and 304L stainless steel. The AWS designation E308L-16 decodes as: \"E\" = electrode; \"308L\" = 18-8 chromium-nickel chemistry with low carbon (≤ 0.04 %); \"-16\" = rutile-basic flux enabling AC and DCEP welding in all positions. Like all Excalibur stainless rods, the 308L version uses tightly controlled flux chemistry to ensure consistent ferrite content (FN 3–10 typical), which prevents hot cracking in the austenitic weld metal during rapid solidification. The \"L\" (low carbon) classification means post-weld sensitization — the precipitation of chromium carbides that depletes HAZ chromium and creates corrosion pathways — does not occur even in thick multi-pass welds.

Low carbon prevents sensitization — the precipitation of chromium carbides at grain boundaries — which can lead to intergranular corrosion in welded joints exposed to aqueous media. For any food, pharmaceutical, or corrosion-critical application, specify E308L-16.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use 308L to weld 304H stainless?\u003c\/strong\u003e\u003cbr\u003e\n304H contains higher carbon (0.04–0.10 %) for elevated-temperature creep strength. E308L-16 does not match the elevated-temperature strength of 304H weld metal. For high-temperature service (above 1100 °F), use E308H-16. For ambient-temperature service or repair, E308L-16 is acceptable — confirm with the applicable code.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is the ferrite number important in 308L weld metal?\u003c\/strong\u003e\u003cbr\u003e\nA small amount of delta ferrite (FN 3–10) in the fully austenitic weld metal acts as a hot cracking inhibitor. Pure austenite has a continuous grain structure through which solidification cracks can propagate. Ferrite creates discontinuities that arrest crack propagation. Too much ferrite (FN \u0026gt; 15) reduces impact toughness and corrosion resistance.

Austenitic stainless steel weld metal (E308L type) maintains excellent impact toughness down to -320 °F and is widely used for LNG, LOX, and liquid nitrogen service.

For any welding performed on 304\/304L, the E308L-16 electrode (Excalibur 308L) is the standard filler metal recommendation. The 18% chromium and 10% nickel in the weld metal deposit match the 304 alloy system, providing equivalent corrosion resistance and austenitic structure in the weld metal and HAZ. The L-grade carbon limitation (0.04% max) prevents sensitization — a critical concern for food processing, pharmaceutical, and water treatment applications where intergranular corrosion at weld HAZs would compromise product purity or pipe integrity. Passive film restoration (passivation) after welding — typically with nitric acid or citric acid solution per ASTM A380 or ASTM A967 — restores the full corrosion resistance of the weld and adjacent HAZ surface. For all food, pharmaceutical, and potable water applications, specify post-weld passivation in the fabrication procedure.

It is the E309L-16 stainless welding rod specified in virtually every dissimilar stainless-to-carbon-steel procedure and stainless overlay application.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is the Lincoln Excalibur 309L E309L-16 Welding Rod?\u003c\/h2\u003e\n\u003cp\u003eExcalibur 309L is Lincoln Electric's E309L-16 SMAW electrode for dissimilar and overlay welding. The AWS designation E309L-16 means: \"E\" = electrode; \"309L\" = overalloyed 22-25 Cr \/ 12-14 Ni chemistry with low carbon (≤ 0.04 %); \"-16\" = rutile-basic flux with AC and DCEP operation in all positions. The 309 chemistry is intentionally richer in chromium and nickel than 308 or 316 — this over-alloying is deliberate: when you weld a 309L electrode across a dissimilar joint where carbon steel dilutes the pool, the excess Cr and Ni in the wire compensate for that dilution and maintain a final weld metal composition with adequate chromium for corrosion resistance and adequate nickel for austenite stability. Without this buffer, carbon-steel dilution into a 308-type filler would shift the weld metal into a martensitic or ferritic composition with poor corrosion resistance and potential for cracking. The \"L\" designation (≤ 0.04 % carbon) ensures that even multi-pass dissimilar welds and multiple overlay layers do not sensitize and corrode in service. Excalibur 309L is the workhorse of stainless clad vessel fabrication and dissimilar weld repair throughout chemical processing, nuclear, power generation, and offshore industries.\u003c\/p\u003e\n\n\u003ch2\u003eAWS Classification \u0026amp; Specs — E309L-16 Welding Rod\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eProperty\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAWS Classification\u003c\/td\u003e\n\u003ctd\u003eE309L-16\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAWS Standard\u003c\/td\u003e\n\u003ctd\u003eAWS A5.4\/A5.4M\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCarbon (max)\u003c\/td\u003e\n\u003ctd\u003e0.04%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eChromium\u003c\/td\u003e\n\u003ctd\u003e22.0–25.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eNickel\u003c\/td\u003e\n\u003ctd\u003e12.0–14.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTensile Strength (min.)\u003c\/td\u003e\n\u003ctd\u003e74,000 psi (510 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eYield Strength (min.)\u003c\/td\u003e\n\u003ctd\u003e54,000 psi (372 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eElongation (min.)\u003c\/td\u003e\n\u003ctd\u003e30%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlux Type\u003c\/td\u003e\n\u003ctd\u003eRutile-basic (-16)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003eAC, DCEP\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePositions\u003c\/td\u003e\n\u003ctd\u003eAll\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDiameters\u003c\/td\u003e\n\u003ctd\u003e3\/32, 1\/8, 5\/32, 3\/16 in\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eBest Applications for E309L-16 Stainless Welding Rods\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDissimilar welds: stainless steel to carbon steel\u003c\/strong\u003e — piping transitions, flanged connections, and structural stainless-to-carbon attachment welds.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStainless overlay cladding on carbon steel\u003c\/strong\u003e — corrosion-resistant lining on the internal surfaces of carbon steel pressure vessels, tanks, and reactors.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButtering layer before welding 304\/316 stainless to carbon steel\u003c\/strong\u003e — E309L is applied as a buttering pass on the carbon steel side to create an austenitic transition layer before the final dissimilar joint weld.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRepair welding on stainless-clad pressure vessels\u003c\/strong\u003e — restoring cladding integrity on corroded or cracked stainless overlay on carbon steel shells.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-temperature dissimilar welds (up to 800 °F service)\u003c\/strong\u003e — 309L provides adequate oxidation resistance and stability for moderate-temperature dissimilar service.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNuclear and power generation applications\u003c\/strong\u003e — E309L-16 is widely used for stainless-to-carbon dissimilar welds in nuclear island and balance-of-plant systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to Use Excalibur 309L — Amperage, Polarity \u0026amp; Position\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eDiameter\u003c\/th\u003e\n\u003cth\u003eAmperage Range\u003c\/th\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e3\/32 in (2.4 mm)\u003c\/td\u003e\n\u003ctd\u003e55–80 A\u003c\/td\u003e\n\u003ctd\u003eThin wall, buttering passes\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1\/8 in (3.2 mm)\u003c\/td\u003e\n\u003ctd\u003e70–115 A\u003c\/td\u003e\n\u003ctd\u003eStandard dissimilar joints, overlay\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e5\/32 in (4.0 mm)\u003c\/td\u003e\n\u003ctd\u003e100–145 A\u003c\/td\u003e\n\u003ctd\u003eMedium-section overlay, fill passes\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e3\/16 in (4.8 mm)\u003c\/td\u003e\n\u003ctd\u003e130–175 A\u003c\/td\u003e\n\u003ctd\u003eHeavy overlay and fill passes\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eDilution control:\u003c\/strong\u003e For overlay applications, minimize penetration into the carbon steel base to reduce dilution.

Carbon steel dilutes the Cr-Ni content of a standard 308-type filler, potentially shifting the weld metal composition toward a martensitic or ferritic structure with poor corrosion resistance and risk of cold cracking. The over-alloyed 309L chemistry (22–25 Cr, 12–14 Ni) compensates for this dilution, maintaining a corrosion-resistant austenitic weld metal composition even with 30–40 % carbon steel dilution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many layers of E309L overlay do I need on carbon steel?\u003c\/strong\u003e\u003cbr\u003e\nTwo layers minimum is the industry standard for ensuring the top surface of the overlay has adequate chemistry to meet Type 304 or 316 corrosion resistance requirements.

The fundamental challenge is managing dilution: when the molten pool simultaneously melts both stainless steel (austenitic) and carbon steel (ferritic\/pearlitic), the resulting weld metal composition is a blend of both. If a standard 308L-type filler is used without compensation, carbon steel dilution shifts the weld metal out of the austenitic field into a duplex or martensitic microstructure — potentially brittle and certainly lacking the corrosion resistance needed for stainless service. Excalibur 309L's overalloyed chemistry (22–25% Cr, 12–14% Ni) is specifically designed to withstand 30–40% carbon steel dilution while remaining in the austenitic field on the Schaeffler or WRC-1992 constitution diagram. For engineers calculating expected dilution and predicting final weld metal composition, Lincoln provides Excalibur 309L's nominal deposit chemistry and a recommendation to consult the WRC-1992 diagram for specific dilution scenarios. Ferrite Number (FN) prediction from the diagram helps confirm that the final weld metal will have sufficient ferrite (FN 3–10) to resist hot cracking without excessive ferrite that would reduce toughness or corrosion resistance. The E309L-16 classification under AWS A5.4 ensures Lincoln's production chemistry control maintains this predictable behavior lot-to-lot.\u003c\/p\u003e","brand":"Lincoln Electric","offers":[{"title":"3\/32 in, 8 lb Easy Open Can (ED033097)","offer_id":43638095577239,"sku":"ED033097","price":179.76,"currency_code":"USD","in_stock":true},{"title":"3\/32 in, 8 lb Easy Open Can (ED033098)","offer_id":43638096265367,"sku":"ED033098","price":139.44,"currency_code":"USD","in_stock":true},{"title":"3\/32 in, 8 lb Easy Open Can (3-Pack) (ED033100)","offer_id":43638097674391,"sku":"ED033100","price":122.16,"currency_code":"USD","in_stock":true},{"title":"3\/32 in, 8 lb Easy Open Can (3-Pack) (ED033943)","offer_id":43639131668631,"sku":"ED033943","price":501.7,"currency_code":"USD","in_stock":true},{"title":"1\/8 in, 8 lb Easy Open Can","offer_id":43638096396439,"sku":"ED033099","price":122.8,"currency_code":"USD","in_stock":true},{"title":"1\/8 in, 10 lb Easy Open Can (3-Pack) (ED033101)","offer_id":43638098231447,"sku":"ED033101","price":211.35,"currency_code":"USD","in_stock":true},{"title":"1\/8 in, 10 lb Easy Open Can (3-Pack) (ED033944)","offer_id":43639137599639,"sku":"ED033944","price":194.76,"currency_code":"USD","in_stock":true},{"title":"5\/32 in, 10 lb Easy Open Can (ED033095)","offer_id":43638092759191,"sku":"ED033095","price":200.28,"currency_code":"USD","in_stock":true},{"title":"5\/32 in, 10 lb Easy Open Can (ED033102)","offer_id":43638099214487,"sku":"ED033102","price":320.56,"currency_code":"USD","in_stock":true},{"title":"3\/16 in, 10 lb Easy Open Can","offer_id":43638099804311,"sku":"ED033103","price":219.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7140\/4695\/files\/lincoln-ed033097-excalibur-309309l-16-stick-smaw-welding-rod-332x12-in-3-8-lb-easy-open-cans-lincoln-electric.jpg?v=1765594688"}],"url":"https:\/\/weldingmart.com\/collections\/stainless-steel-welding-rods.oembed?page=2","provider":"WeldingMart.com","version":"1.0","type":"link"}
