A286 AMS 5737
A286 AMS 5737 is an iron based superalloy designed for applications requiring high strength and good corrosion resistance at temperatures up to 1300°F (704 °C). Rockwell Industries A-286 AMS 5737 attains its high strength levels through a solution heat treatment followed by a precipitation hardening. Its oxidation resistance remains high for continuous service to 1500°F.
