Nimonic 80A Superalloy is a nickel-chromium based material which offers excellent corrosion and oxidation resistance.
The alloy is precipitation hardenable with additional alloying elements of aluminium, titanium and carbon. The product is a wrought, age-hardenable material developed to operate in service temperatures up to 815° C (1500°F). Nimonic 80A performs well in any application where high temperature and continual stresses is a significant consideration. Traditionally, it is used in applications requiring these characteristics such as gas turbines and in nuclear generators; in the motorsport sector, material applications include exhaust valves in racing engines and spindles and fasteners.
Supplied in the solution treated condition, which makes it easier to machine, subsequent ageing treatment results in very high mechanical performance properties with outstanding resistance to creep and fatigue.
The corrosion resistance of Nimonic 80A in oxidising atmospheres is excellent - this includes heating and cooling conditions. This protection is due to the chromium oxide film formed on the surface of the alloy, which also offers resistance at elevated temperatures. Machinability of the alloy is also improved; it can be readily formed and welded using conventional welding methods.
Product characteristics include:
Nimonic 80A applications include engine exhaust valves and spindles, fasteners and gearboxes.
