Nickel Alloy A-286 – Properties, Applications and Technical Data
Alloy A-286 is a high-strength iron-nickel-chromium alloy developed for applications requiring high strength, good oxidation resistance and stable performance at elevated temperatures.
The alloy is often used in the aerospace industry, the energy sector and other technically demanding environments where components are exposed to high temperatures, mechanical stress and oxidative atmospheres.
A-286 combines good creep resistance, high temperature strength and good corrosion resistance, making the material suitable for safety-critical components.
Properties of Alloy A-286
Alloy A-286 is a precipitation-hardened iron-nickel-chromium alloy that retains its mechanical strength at temperatures up to approximately 700 °C.
The alloy is often used where high-strength stainless steels are not sufficient and where both temperature and oxidation resistance are important factors.
