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.See also Project 70/Project 7000 Type 316, Alloy Digest SS-339, revised October 1997, and Project 70/Project 7000 stainless type 316L, Alloy Digest SS-515, revised July 1997. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-878.
