AK Steel Type 301 is an austenitic chromium-nickel stainless steel that provides high strength and good ductility when cold worked. It is a modification of Type 302, in which the chromium and nickel contents are lowered to increase the cold-work-hardening range. This permits higher tensile strengths to be achieved by rolling with a lower loss of ductility than with Type 302. The high-strength properties of Type 301 make it ideally suited to structural and transportation applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-861.
