welding filler metal for SS321
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.
