RAAJMIG ER 310 (AWS/SFA-5.9: ER310)

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

Classification:

AWS/SFA-5.9 : ER310
BS : 25.20H
DIN 8556 : WK. 1.4842

Characteristics:

ER310 is a fully austenitic stainless steel welding wire. The weld metal contains no ferrite and provides excellent resistance to heat. It ensures strong, durable, and heat-resistant welds suitable for high-temperature applications.

Applications:

Welding of 25% Cr – 20% Ni stainless steels
Joining similar heat-resistant steels
Suitable for welding carbon steel to 18/8 stainless steel and fully austenitic stainless steel
Recommended for service temperatures up to 1100°C
Used in cladding applications

Shielding Gas:

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