View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Carpenter Project 70+ Type 316/316L is a modified version of Type 316/316L stainless steel with improved machinability when compared to conventional 316/316L. The alloys are non-hardenable austenitic chromium-nickel-molybdenum steels and are good general-purpose products for simple and complex parts.
