AMS 5734 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.
Premium aircraft quality with multiple melting and Consumable Electrode Remelting is required.
Material is in the form of Bars, Wire, Forgings, and Tubing in the solution treated condition.
Solution heat treatment temperature is 1650 deg F
Samples of the material are precipitation heat treated at 1300 to 1400 deg F to verify response
to heat treatment of parts during manufacture
