┃ Overview

UNS N07080 is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded.

┃ Application

Aerospace Industry: Aircraft engine components, exhaust systems, and afterburner parts

Gas Turbines: Turbine blades, turbine discs, and combustor cans

Chemical Processing: Reactors, heat exchangers, and furnace components

Nuclear Industry: Reactor core components and fuel handling systems

Power Generation: Steam turbines and boiler components

Automotive Industry: Exhaust valves, turbocharger components, and piston rings


┃Corrosion Resistance

Nimonic 80A exhibits good corrosion resistance, particularly in high-temperature and corrosive environments. It demonstrates excellent oxidation resistance, making it suitable for high-temperature applications.Alloy 80A also withstands attack from acidic and alkaline environments, making it suitable for chemical processing. Additionally, it has resistance to stress corrosion cracking, making it suitable for applications under combined stress and corrosive conditions.


┃Machining

Nimonic 80A should be in the fully heat treated condition for all machining operations. The high material hardness in this condition requires the use of stringent machining techniques.


┃Welding

Nimonic 80A is readily joined by any of the resistance welding processes. For section thicknesses up to about 5 mm, fusion welding by conventional processes such as T.I.G. or M.I.G. is satisfactory. For section thicknesses greater than 5 mm, electron beam, friction, inertia and flash-butt welding have all been successfully used. The normal precautions for welding nickel alloys should be observed and welding should be carried out on solution treated material. Post-weld heat treatment is necessary to achieve optimum properties.
