Abstract AISI No. 617 is a general purpose hardenable stainless steel which can be heat treated to the highest hardness and strength level. It is recommended for many applications where corrosion and oxidation resistance coupled with high strength and wear resistance are required as in bearings, cams and rollers in aircraft and missile fields. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-231.
