AMS 5525 is a specification for A286 aka UNS S66286.
It 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..
Material is in the form of sheet, strip, and plate in the solution treated condition.
Solution heat treatment temperature is 1800 deg F
Samples of the material are precipitation heat treated at 1325 deg F to verify response to heat
treatment of parts during manufacture
