SMAW · Stainless steel
E310-16
A high chromium, high nickel rod for furnace and heat treatment hardware, where the deposit must resist scaling at temperatures that would ruin ordinary stainless.
What the designation means
Point at any character to see what it claims. The classification is a sentence written in fields, not a product name.
- ECovered electrode for shielded metal arc welding.
- 310A fully austenitic deposit in the nominal 26 chromium, 21 nickel class, formulated for high temperature scaling resistance.
- -16Titania bearing covering, usable on alternating current or direct current electrode positive.

Typical uses
- Furnace parts, burner components, and heat treatment fixtures
- High temperature ducting and retorts
- Certain dissimilar joints where a fully austenitic deposit is wanted
How it runs
- Fully austenitic deposit with essentially no ferrite, so hot cracking control depends on low heat input
- Sluggish, ropey puddle that needs deliberate stringer technique
- Heavy slag that must be removed completely between passes
- High thermal expansion, so distortion and restraint need planning
Storage and handling
Store sealed and dry in a warm cabinet, and keep exposure short once the container is opened.

SMAWE309L-16The go-to rod for joining stainless to carbon steel, because its extra chromium and nickel keep the diluted deposit austenitic instead of hard and crack prone.SMAWE308L-16The default stainless rod for welding the common 18-8 grades, giving a low carbon austenitic deposit with enough ferrite to resist hot cracking.GTAWERNiCr-3A nickel-chromium rod used for nickel alloy base metals, dissimilar joints, and overlay, where its niobium addition resists cracking through heavy dilution.
