Re: [MW:35233] Re: Filler wire for 321H

0.4% C is not correct for the 321H material.

The carbon content of AISI 321H is typically in the range of 0.04% to 0.10%. 

ER347 is the best choice due to its niobium stabilization and  carbon content of the filler is within the appropriate range (0.04% to 0.10%).

AWS 5.4  ER 347 #0.08%.

ER347 is not meeting min C % requirement of 0.4%.

In that case, ER347 cannot be used. then which filler to be used?

ER 316H lacks the niobium stabilization that 321H requires for high-temperature applications 

and potentially leading to sensitization/reduced corrosion resistance in the heat-affected zone 

ER347 is the preferred filler material.

Use ER316H.

We are successfully welding S321H, as per Russian GOST codes requirement.

Best use ER347H, Nb stabilized 18 10 Cr Ni steel
