A-286 alloy is an age-hardenable iron base superalloy for applications requiring high strength from -320°F up to 1000°F long time, 1300-1500°F short time. Oxidation resistance is high for continuous service to 1500°F, intermittent to 1800°F. Aqueous corrosion resistance is comparable to 316/316L stainless. Heat treatment according to AMS 5525 requires a solution anneal at 1800°F, air cool. Age at 1325°F for 16 hours and then air cool.
