E6011 vs ER308L: 42% composition overlap. Significantly different materials serving different application areas.
E6011 vs ER308L
Side-by-side chemical composition and mechanical property comparison.
Overview
E6011
High-cellulose potassium coated SMAW electrode — the AC-capable version of E6010. Deep penetrating, forceful arc with fast-freeze slag. Runs on both AC and DCEP, making it usable with smaller transformer-type welding machines. Tensile strength 60 ksi (414 MPa). Same cellulose coating system as E6010 — do NOT rebake. Used for pipeline root passes (when DCEP machine not available), field erection, maintenance welding and dirty/rusty steel.
ER308L
Low-carbon austenitic stainless steel welding wire — the standard filler for joining 304 and 304L stainless steels. The L (low carbon ≤0.03%) prevents sensitization and intergranular corrosion in the heat-affected zone. Used for TIG (GTAW) and MIG (GMAW) with pure argon or Ar/CO2 shielding. Produces fully austenitic-ferritic weld metal with 5-15 FN (Ferrite Number) for crack resistance. Used for food processing equipment, chemical tanks, pharmaceutical vessels, and architectural stainless fabrication.
