E347-16 is an AWS A5.4 niobium-stabilized austenitic stainless SMAW electrode with 75 ksi minimum tensile and ~19 Cr / 10 Ni / Nb chemistry, designed for welding 347, 321, and other niobium- or titanium-stabilized austenitic grades used in high-temperature service. The niobium addition prevents knife-line attack at sustained 800-1500 deg F service temperatures. The lime-titania (-16) coating delivers smooth arc and X-ray quality welds. Runs on AC or DC+ in all positions.
Is this the same electrode as the parent Lincoln Excalibur 321-16 grade, just in a different package?
Yes. SKU ED034996 is the same AWS A5.4/A5.4M E347-16 classification as every other size in the Lincoln Excalibur 321-16 family. The only difference is diameter (1/16 in) and package format (10 lb easy-open can). Polarity, position, and tensile properties are identical to the parent grade.
How many rods are in this 10 lb easy-open can?
Approximately varies by package weight. Exact count varies with manufacturing tolerance but a 10 lb easy-open can of 1/16 in Lincoln Excalibur 321-16 typically contains in this range.
What is the shelf life if I do not use them all?
Sealed containers store indefinitely in a dry environment. Stainless SMAW electrodes are sensitive to moisture pickup; keep opened rods in a dry rod oven at 200-300 F and rebake per manufacturer instructions if exposed to humid conditions for extended periods.
What diameter should I use for common applications?
1/16 in is well-suited for general fabrication work. Heavier base metal and higher deposition typically calls for one diameter up; thinner sheet and root passes go one diameter down. See the parent grade page for full diameter-to-amperage guidance.
Can I mix this size with other diameters on the same job?
Yes, provided your procedure qualification (WPS) covers the diameter range. Many shops use one diameter for root, one for fill, and one for cap. All sizes within Lincoln Excalibur 321-16 share identical mechanical properties (AWS A5.4/A5.4M E347-16) so weld metal chemistry is consistent across passes.
Do I need to rebake these after the can is opened?
Recommended for code-quality stainless work. Keep opened rods in a heated rod oven at 200-300 F. If rods have been exposed to humid conditions for extended periods, rebake at the temperature specified on the manufacturer data sheet (typically 500-700 F).
Does this size require a special holder or stinger?
Use an electrode holder rated for the amperage range above (see grade spec). Most general-purpose stinger holders (e.g. 300-500 A class) handle 1/16 in Lincoln Excalibur 321-16 without issue. For sustained high-amperage runs on larger diameters, a 500 A or higher holder is recommended.
Is this Buy America compliant?
This specific SKU is not the Buy America variant. Lincoln Excalibur 321-16 may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
