RE: [MW:24742] RE: 24723] welding filler metal for SS321

This an Air Cooler, and the operating temperature is +350C.

What's the process fluid and the design temperature?

Dear Pradip

Since the operating temperature is below 400C, I think the E308LSi can be a good choice, Are you agree?

Regards,

Himan

Hi Himan,

 

What's proposed by ESAB is not correct. Please seethe two attachments showing highlighted texts. S.S 321 is a Titanium stabilized steel. Hence the matching weld metals also  shall be  stabilized.

 

Titanium gets oxidized fast when it's added through coating.  Hence other stabilizers such as Nb has to be added to the weld puddle to provide the stabilized weld metal as well as provide the high temperature Creep Properties. Thus 347 electrodes/fillers are the only solution.

 

Hope it clears your doubt.

 

Thanks.

Dear Experts

 

Refer to API582 table A-2 proposed filer to weld SS321 to SS321 is E347-XX/ER-347 but some manufacturers such as ESAB propose E/ER-308LSi to this base material (SS321 to SS321) operating temperature is +350 C,

would you please advise in this issue.

 

Regards,

H.Nikdin
