Also referred to as A286 stainless steel, Alloy® A-286 essentially is an austenitic superalloy that is iron and nickel-based. This alloy is widely used for applications that require superior strength, as well as corrosion resistance up to 704˚C (1300˚F). Alloy® A-286 is also used for lower stress applications at high temperatures. The key mechanical properties of this austenitic superalloy tend to be developed by distinct precipitation hardening and annealing treatments.
The Alloy® A-286 boasts of having incredibly high-temperature oxidation resistance and is known to be designed specially to maximize the properties of stress and creep rupture, with a bit of reduction in strength. This alloy has the capacity to attain superior strength levels when aged subsequent to cold work. It additionally has quite wide applications in high-temperature springs and fasteners.

Resistance capacity against oxidation and corrosion
The type A286® Alloy content is renowned for being similar in molybdenum, chromium, and nickel to a few of the austenitic stainless steels available. This alloy subsequently is known to have a certain level of aqueous corrosion resistance that can be compared to that of various austenitic stainless steels. In the scenario of an elevated temperature service, the corrosion resistance level to atmospheres like the ones experienced in jet engine applications tends to be as incredible as 704°C. The oxidation resistance in the case of A286® is also quite high for continuous service up to 816°C, as well as intermittent service up to 982°C.
