Nimonic 80a, Nickel Alloy 80a

Typical Applications

Bolts

Exhaust valves

Gas turbine components

Tube supports in nuclear steam generators

Alloy 80A (alternatively known by Special Metals trade name Nimonic 80A) is a nickel chromium alloy similar to Alloy 75 but made precipitation hardenable by additions of aluminium and titanium.

Alloy 80A has good corrosion and oxidation resistance and high tensile and creep rupture properties at temperatures up to 1500 deg F.
