JIS Y310
AWS ER310

Description and Applications
HM310 is a gas metal arc welding wire to be used with Ar+0.5~2%O2 shield gas. Deposited metal contains a full austenitic structure with excellent corrosion, acid, and heat resistibility.

Welding of 25% Cr-20% Ni stainless steel, dissimilar metals such as 18% Cr-8%Ni stainless steel to carbon steels for petroleum and chemical industries.
 
Guideline in Usage
When high X-ray quality is required, stable spray transfer mode should be maintained with low current and slow welding speed using a pulsed arc and power source.
