4.Characteristics：
Precipitation hardening alloys, high temperature ( up to 815 ° C) for excellent properties.
5.Applications：
Diesel engine exhaust valve of Vessels, tanks mainly made from Nimonic 80 a forging. High heat resistance,
high strength at high temperature, large deformation resistance, increased the difficulty of the forging. Suitable for
manufacturing bolt, exhaust valve of the combustion chamber.
