A286 alloy is an age-hardenable iron-nickel-chromium superalloy for applications requiring long-term high strength from -195°C-538°C. If short-term high strength properties are acceptable, the alloy can be used between 704-816°C. Oxidation resistance is high for continuous service to 816°C and intermittent to 982°C.
Aqueous corrosion resistance of A286 is comparable to 316/316L stainless grade.
Heat treatment according to AMS 5525 requires a solution anneal at 982°C air cool, age at 718°C for 16 hours and then air cool.
