CarTech 201 Modified is a nitrogen-strengthened, chromium-manganese-nickel, austenitic stainless steel that provides substantially higher yield and tensile strength than CarTech 304, and has general-corrosion resistance between that of CarTech 430 and CarTech 304. Compared with CarTech 201 (UNS S20100), CarTech 201 Modified has a lower nickel content, which results in higher-strength levels after cold working. This datasheet provides information on composition and physical properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1319. Producer or source: Carpenter Technology Corporation.
