CARPENTER STAINLESS 18-18 PLUS is an 18 chromium-18 manganese austenitic stainless steel which provides twice the yield strength of AISI Type 304 stainless steel and corrosion resistance similar to AISI Type 316 in some media. It has excellent ductility and toughness and good high-temperature strength. Although Carpenter 18-18 Plus contains no nickel, it is nonmagnetic both in the annealed condition and after severe cold forming. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-344.
