TIG Wire ER630 grade is a hardening martensitic stainless steel used for welding materials of similar chemical composition such as
17-4 and 17-7 plates, The mechanical properties of this alloy tig wire are greatly influenced by heat treatment.
ER630 can be used in the welded condition, or may be heat treated to obtain higher strength.
