A286 aka UNS S66286 is a precipitation hardening high strength corrosion resistant steel alloy.
It is used in applications requiring moderate strength at temperatures up to 1300 deg F or
oxidation resistance at temperatures up to 1500 deg F.
It has an austenitic structure and low permeability that makes it useful in some nonmagnetic
Premium aircraft quality with multiple melting and Consumable Electrode Remelting is required
by most aerospace standards.
Mechanical properties depend on the specifics of the solution treatment and precipitation
treatments as well as any cold work introduced in manufacture.
Solution heat treatment temperatures range from 1650 to 1800 deg F
Precipitation heat treatment temperatures range from 1300 to 1400 deg F
