Atlas 301 is a high work-hardening rate austenitic stainless steel. It can be supplied with a tensile strength of up to and over 1300 MPa (189 ksi) in strip and wire forms, to produce tempers in the range of 1/16 Hard to Full Hard. The controlled analysis of Atlas 301 enables it to retain sufficient ductility in conditions up to 1/2 Hard and allows it to be roll or brake formed into aircraft, architectural, and particularly rail car structural components. However, 3/4 Hard to Full Hard tempers should be used whenever high wear resistance and spring features are required in components of simple form designs. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1349. Producer or source: Atlas Steel.
