Nimonic 81 (UNS N06002)
Category: NIMONIC
Overview
NIMONIC alloy 81 is a wrought nickel alloy hardened by controlled additions of titanium and aluminum, and designed to provide enhanced resistance to high temperature corrosion coupled with good high temperature strength. It has excellent hot corrosion resistance due to its high chromium content. Elevated temperature strength characteristics are similar to those of NIMONIC alloy 80A. Melting, hot-working, cold-working and machining practices are also broadly similar to those for NIMONIC alloy 80A. Applications include components for gas turbines, piston engine exhaust valves, and heat-exchange plant subject to attack by deposits resulting from the combustion of impure fuels, particularly by alkali metal sulfates and chlorides.
