AMS 5737 A286 Stainless Steel Round Bar

what is ams 5737 specification?

AMS 5737 is an aerospace specification for A286 stainless steel, an age-hardenable alloy used for high-strength, corrosion-resistant parts in high-temperature environments like jet engines, superchargers, and industrial turbines, specified for bars, wire, forgings, and tubing after a specific heat treatment (solution treated at 1650°F and aged).

 

what is AMS 5737 A286 Stainless Steel Round Bar?

AMS 5737 A286 stainless steel round bar is a high-strength, iron-based austenitic high-temperature alloy specifically designed for demanding aerospace and high-temperature applications. Supplied in bar form, it offers excellent strength, good corrosion resistance, and outstanding performance at temperatures up to 1300°F (704°C), as well as excellent performance at cryogenic temperatures. It is commonly used in jet engine components, fasteners, and turbines.
