Nimonic / Alloy 80A with Good Corrosion and Oxidation Resistance
Description:
Nimonic alloy 80A (UNS N07080 / W. Nr. 2.4952&2.4631) is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815℃ (1500ºF). It is produced by high-frequency melting and casting in air for forms to be extruded. Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available. NIMONIC alloy 80A is currently used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves.

Applications:
Nimonic 80A could be used for gas turbine components such as blades, rings and plates, etc. Other applications include bolts used in temperature and stress limit, the combustion engine exhaust valve and other high strength parts. For example, the nuclear boiler tube bracket, etc. The alloy is also suitable for high temperature springs, especially in the condition of continuous stress under the working conditions.
Features:
1.Good creep resistance performance at temperature 650°C~850°C.
2.Good resistance to oxidation at temperature 650°C~850°C.
3.Good cold and hot work performance.
4.Good resistance to fatigue in serve work conditions.
