Carpenter type 204-Cu is a low-nickel, Manganese containing, austenitic stainless steel with copper. The copper provides a reduced work hardening rate for superior forming when compared to other 200 series stainless steels. This datasheet provides information on composition, physical properties, and tensile properties as well as fatigue. It also includes information on low and high temperature performance, corrosion and wear resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-711. Producer or source: Carpenter.
