Product FEATURE
Precipitation hardenable alloy with excellent elongation properties at high temperatures (up to 815°C).
Product application
Exhaust valves for marine and tank diesel engines are mainly made of Nimonic 80A.
Nimonic 80A has high heat resistance, high strength and high deformation resistance at high temperature.
Nimonic 80A has high heat resistance, high strength and high deformation resistance at high temperature, which increases the difficulty of forging and molding. Suitable for
The exhaust valves for bolts and combustion chambers are made of Nimonic 80A.
