RAAJMIG ER308H (AWS/SFA-5.9: ER308H)

Stainless Steel Continuous & Cut Length Solid Welding Wire for MIG/TIG Welding

Classification:

AWS/SFA-5.9 : ER308H

Characteristics:

ER308H is a stainless steel welding wire with restricted carbon content (0.04–0.08%), designed for welding austenitic stainless steels like 301, 302, and 304H. It deposits high-carbon weld metal suitable for high-temperature applications, producing smooth, even, and shiny weld beads.

Typical Applications:

Welding un-stabilized austenitic stainless steels such as 301, 302, 304H
Chemical and petrochemical industries
Pulp and paper industries
Applications requiring high tensile strength, e.g., agricultural implements, automobiles, construction

Shielding Gas:

Welding with 100% Ar gas or Ar + 2% O₂ gas.
