MAR-M Alloy 421 is a precipitation hardened nickel-base superalloy developed to provide a good combination of high strength, ductility, sulfidation resistance, and stability. It is recommended for gas turbine applications. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-141. Producer or source: Martin Metals Division.
