Chinese Manufacturer High Quality Nimonic 80A Pipe Plate Bar

GH80A is a R-phase dispersion strengthened superalloy based on nickel chromium and added with aluminum and titanium. Except that the aluminum content is slightly higher, it is similar to GH4033. The service temperature is 700 ~ 800 ℃ and has good creep and oxidation resistance at 650 ~ 850 ℃. The alloy has good cold and hot workability. It mainly supplies hot-rolled bars, cold-drawn bars, hot-rolled plates, cold-rolled plates, strips and ring parts. It is used to manufacture engine rotor blades, guide blade supports, bolts, blade lock plates and other parts.

Nimonic 80A has the following characteristics
Main features: precipitation hardening alloy, excellent tensile properties at high temperature (up to 815 ° C).

Application example
The exhaust valve of diesel engine for ship and tank is mainly forged by Nimonic 80A,Nimonic 80A has high heat resistance, high strength at high temperature and large deformation resistance, which increases the difficulty of forging Suitable for manufacturing bolts, exhaust valves for combustion chambers.
