Special Metals NIMONIC™ Alloy 81

 

Subcategory: Superalloy; Nickel Base

Key Words: Nickel-Chromium Alloy

Material Notes:
Nickel content as remainder. 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%. The alloy also has good tensile and rupture strength and creep resistance at elevated temperatures. Used 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 sulfates and chlorides. The standard product form is round.
