Re: [MW:34394] Re: WPS FOR 321H

Dear Sir,

When welding 304H to 321H stainless steel, we typically use a 347 filler material which contains a stabilized form of stainless steel, and less sensitive to intergranular corrosion, and has a high resistance to oxidation.

Best regards,

I need to replace the roof and bottom plate of a tank. I need to select a welding rod that is compatible with 304H-321H steel. Would 347 welding rod work?

Dear Ashish 

What is service of the equipment ?(Operating temperature ?)?

The ER321  is compatible wire .

for TYP 347/321 base metals -ER 16 8 2 is deployed when the weld need less FN   when operating temperatures  are higher (> 500 Deg C ) 

Thanks
