Alloy 80A (Nimonic® alloy 80A) is a wrought, age-hardenable nickel-chromium alloy. Alloy 80A is similar to alloy 75 but made precipitation hardenable by additions of aluminium and titanium. Alloy 80A has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 815ºC (1500ºF). Vacuum refined versions are also available. Alloy 80A is used for gas-turbine components (blades, rings, discs), bolts, tube supports in nuclear generators, exhaust valves in internal combustion engines and has many other offshore/marine, automotive and electrical applications.

Fabrication

Machinability

The conventional machining techniques used on iron alloys may be used for this alloy. This alloy work-hardens during machining.

 Welding

NIMONIC alloy 80A can be welded using common techniques, using a matching filler metal. A prerequisite for welding is that the metal should be solution treated. Fusion welding by tungsten inert gas welding and metal inert gas welding will be suitable for this alloy.

 Hot working

NIMONIC alloy 80A can be hot worked at temperature ranges of 1050-1200°C (1920-2190°F).

 Forging

NIMONIC alloy 80A can be hot forged at temperatures in the range of 982-1176°C (1800-2150°F).

Cold working

Cold working may be done on the alloy.

Annealing

NIMONIC alloy 80A should be annealed at 1079°C (1975°F) for about 8 hours and air cooled.

Applications

The NIMONIC alloy 80A is used in the following applications:

Gas turbine engineering

Automobile exhaust valves

Die-casting inserts and cores

Nuclear boiler tube parts.
