Abstract
CARPENTER 21-12N is an austenitic chromium-nickel stainless steel for valves. It offers excellent high-temperature strength and hardness as well as corrosion resistance to combustion products. This alloy contains 0.15-0.25% nitrogen for increased high-temperature strength. It is widely used as the head material in two piece exhaust valves for both diesel and gasoline engines. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-316. Producer or source: Carpenter.
