E309L-16 (extra-low carbon, ≤0.04% C) is used when corrosion resistance must be maintained in the as-welded condition — food service, chemical processing, and aqueous service. For dissimilar metal welding in standard industrial applications, 309L is generally preferred to allow for future service changes. For known high-temperature service, 309-16 is acceptable.\u003c\/p\u003e\u003cp\u003eWhen should I use E309-16 vs E308L-16?\u003c\/p\u003e\u003cp\u003eUse E309-16 for dissimilar metal welding (stainless to carbon steel) or for welding Type 309\/309S base metal. Use E308L-16 for same-metal welds on Type 304\/304L stainless in corrosion-sensitive applications. The key difference is that E309's higher Cr-Ni content tolerates carbon steel dilution that would compromise an E308L deposit.\u003c\/p\u003e\u003cp\u003eWhat base metal does Harris 309-16 weld?\u003c\/p\u003e\u003cp\u003eHarris 309-16 welds Type 309 and 309S stainless steel base metals (matched composition) and is used for dissimilar metal joints between austenitic stainless and carbon or low-alloy steel.

The higher carbon in standard 309-16 will cause sensitization (carbide precipitation) during the weld thermal cycle, compromising corrosion resistance in the HAZ in aqueous environments.\u003c\/p\u003e\u003cp\u003eWhat is the difference between E309 and E310 stainless rod?\u003c\/p\u003e\u003cp\u003eE309 deposits contain approximately 23% Cr \/ 13% Ni. E310 deposits contain 25–28% Cr \/ 20–22% Ni — significantly higher in both elements. E310 is specified for extremely high-temperature service (above the range where E309 is adequate), severe oxidizing atmospheres, and applications requiring superior hot-strength and oxidation resistance above approximately 2000°F. E309 is used for dissimilar joints and standard high-temperature applications; E310 is reserved for severe high-temperature service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBrowse all stick electrodes:\u003c\/strong\u003e \u003ca href=\"\/collections\/stick-welding-electrodes-rods\"\u003eStick Welding Electrodes \u0026amp; Rods\u003c\/a\u003e — compare with \u003ca href=\"\/products\/harris-309l-stainless-stick-smaw-welding-rod\"\u003eHarris 309L\u003c\/a\u003e for low-carbon dissimilar welding in corrosion service, or \u003ca href=\"\/products\/harris-310-16-stainless-stick-smaw-welding-rod-1-8-x-14-x-10-3101660\"\u003eHarris 310-16\u003c\/a\u003e for ultra-high-temperature and severe oxidation applications.\u003c\/p\u003e\u003ch2\u003eOrdering Harris E309-16 from WeldingMart\u003c\/h2\u003e\u003cp\u003eHarris E309-16 stainless welding rods ship from WeldingMart — this product is in stock and available to add to your cart.
