301 stainless steel weldability:
Stainless steel grade 301 is suitable for all forms of standard welding methods. The use of grade 308L as filler metal is recommended. Welded parts in grade 301 must be subjected to annealing in order to attain maximum corrosion resistance. For grades 301L and 301LN annealing is not necessary after welding. The purpose of welding followed by annealing is to remove the high strength brought about by cold rolling.
