Nimonic 80A Superalloy is a nickel-chromium based material which offers excellent corrosion and oxidation resistance. The alloy is precipitation hardenable by adding aluminium, titanium and carbon and was developed to operate in service temperatures up to 815° C (1500°F).
Alloy 80A has decent machinability and weldability, making it a widely selected alloy for various applications in the petrochemical, gas & generation and other industrial sectors requiring high-strength corrosion resistant alloys capable of operating at elevated temperatures.
80A is available in various sizes and grades, although the most common available one is per ASTM B-637 with heat treatments being solution annealing, stabilization and followed by a precipitation treatment to allow the added aluminium and titanium to precipitate and strengthen the alloy matrix to achieve the desired mechanical properties.
