NICROFER 4221 is a fully austenitic nickel-chromium-iron-molybdenum-copper alloy that is stabilized (against intergranular corrosion) by an addition of titanium. It is resistant to stress-corrosion cracking, pitting corrosion and oxidizing and non-oxidizing hot acids. It has good mechanical properties both at room and at elevated temperatures. It is used in a wide variety of applications up to 540 C (1000 F). This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-283. Producer or source: Vereingte Deutsche Metallwerke AG.
