Abstract

CARPENTER 80-20 ALLOY is a nickel-chromium alloy intended for service at high temperatures. It offers good corrosion resistance to exhaust gases in aircraft piston engines. Considerable quantities of this alloy have been used as welded overlays on valve heads for aircraft engine exhaust valves. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-264. Producer or source: Carpenter.
