it is not 321+321 joints ( if use TIG, 321 can be used,but if we use SMAW, for same combination, we have to use only 347.. it is a 304 +321.

--Snap shot of API RP 582 below recommends either 308 or 347 but it is for SMAW process. ER321 can be used for TIG welding and that is the idea behind the mail. New introduction.Thanks & Regards

AWS A5.9 ER321 is a titanium-stabilized austenitic stainless steel filler metal designed for welding 321 and 347 stainless steels. It has good oxidation and corrosion resistance and can be used for welding in high-temperature applications.
AWS A5.9 ER347 is a niobium-stabilized austenitic stainless steel filler metal designed for welding 321 and 347 stainless steels. It has excellent high-temperature strength and oxidation resistance, making it suitable for welding in severe service conditions.
The selection of the filler metal will depend on the specific application and the welding process being used. It is recommended to consult the applicable code or standard and a qualified welding engineer or metallurgist for specific guidance on selecting the appropriate filler metal for your application.
