ER308 SS TIG WIRE | FEATURES

ER308 Stainless Steel TIG Welding Rod
  • The nominal composition (wt.-%) of ER308 is 21 Cr, 10 Ni.
  • This filler metal is the most popular grade among stainless steels.
  • Balanced chromium and nickel levels provide enough ferrite in the weld for high resistance to hot cracking
  • Solid, corrosion-resistant, chromium-nickel wire for welding austenitic chromium-nickel alloys of the 18% Cr-8% Ni type.
  • Welding process of ER308 SS TIG rod applied to TIG(Tungsten Inert Gas Welding) or GTAW(Gas Tungsten Arc Welding).
