This alloy has the following characteristics:

Main features: Precipitable and hardenable alloy, excellent tensile properties at high temperatures (up to 815 ° C).

Example of use: The exhaust valve of diesel engines for ships and tanks is mainly made of Nimonic 80A. Nimonic 80A has high heat resistance, high strength at high temperature, large deformation resistance, and increased difficulty in forging. Suitable for Manufacture of bolts, exhaust valves for combustion chambers.
