AK Steel Type 304 is a chromium-nickel austenitic stainless steel. It is a variation of the base 18-8 grade, but with higher chromium and lower carbon content. The lower carbon content minimizes carbide precipitation due to welding and reduces its susceptibility to intergranular corrosion. Type 304 is the most versatile and widely used stainless steel grade. It combines good resistance to atmospheric corrosion and to many chemicals, food, and beverages. It has excellent formability. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties as well as fatigue. It also includes information on low and high temperature performance, and corrosion resistance as well as forming and joining. Filing Code: SS-1317. Producer or source: AK Steel Corporation.
