Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.PROJECT 70 STAINLESS TYPE 303DQ is a modification of Project 70 Stainless Type 303 (Alloy Digest, SS-409, June 1982). Type 303DQ is designed and processed to optimize drilling and cut-thread tapping machining operations. Compared with regular Project 70 Stainless Type 303, the Type 303DQ modification will allow faster feeds and speeds, longer drill and tap life and less tap breakage.
