NIMONIC alloy 81
Werkstoff Nr: -
A precipitation-hardenable nickel-chromium alloy with enhanced resistance to high-temperature corrosion. The excellent hot-corrosion resistance of the alloy results from its high chromium content of 30%. It has good tensile and rupture strength and creep resistance at elevated temperatures. For gas turbines, piston-engine exhaust valves, and furnace equipment subject to attack by deposits resulting from combustion of impure fuels, particularly those containing alkali metal sulphates and chlorides.
