ER308H SS TIG WIRE | FEATURES

ER308H Stainless Steel TIG Welding Rod
  • ER308H is the same as ER308, except that the allowable carbon content has been restricted to the higher portion of the 308 range.
  • Provides a high carbon content deposit (0.04% – 0.08%) for high temperature applications.
  • The high carbon deposit provides creep strength and a high tensile strength at elevated temperatures.
  • Solid, corrosion-resistant, chromium-nickel wire for welding austenitic chromium-nickel alloys of the 18% Cr-8% Ni type.
  • Welding process of ER308H SS TIG rod applied to TIG(Tungsten Inert Gas Welding) or GTAW(Gas Tungsten Arc Welding).
