STAINLESS STEELS Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common.The primary alloying additions are chromium and nickel.Ferritic stainless steels are non-hardenable Fe-Cr alloys.Types 405,409,430,422 and 446 are representative of this group.Martensitic stainless steels are similar in Stainless Steels Welding Guide - Lincoln Electricmartensitic stainless steels.Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld.3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr,8-24% Ni + Mn,up to 0.40% C and small amounts of a few other elements such as Mo,Ti,Nb (Cb) and Ta.The balance between the Cr and Ni SUGGESTIONS FOR WELDING STAINLESS STEELHowever,duplex and super duplex stainless steels call for special mention.Welding Requirements To weld stainless steels,three factors are to be considered The type of stainless steel material that is to be welded.
