Nimonic 80A alloy has the following characteristics:

Main features: Precipitation hardening alloy, excellent tensile properties at high temperature (max. 815 ° C).

Example of use: The exhaust valves of diesel engines for ships and tanks are mainly forged with Nimonic 80A. Nimonic 80A has high heat resistance, high strength at high temperatures, large resistance to deformation, and increased difficulty in forging. Manufacture of bolts, exhaust valves for combustion chambers.
