AMS 5731 vs AMS 5732
What material is AMS 5731?
AMS 5731 refers to A286 stainless steel, which is an iron-nickel-chromium high-temperature alloy with high strength, corrosion resistance, and high-temperature resistance up to 1300°F (704°C). It is commonly used in aerospace applications (such as jet engines and fasteners) and high-temperature industrial applications. This material is supplied in various forms such as bars, forgings, and plates, and its properties are enhanced through age hardening heat treatment.
What material is AMS 5732?
AMS 5732 is an aerospace material specification for A-286 stainless steel, a high-temperature iron-based alloy ideally suited for jet engine parts, fasteners, and oil and gas equipment components. This material is available in the form of bars, forgings, tubes, and wires.

AMS 5731 vs AMS 5732
Both AMS 5731 and AMS 5732 refer to A286 alloy, a high-strength, high-temperature resistant stainless steel, but they differ in their heat treatment processes. AMS 5731 undergoes solution treatment at 1800°F (980°C) followed by quenching, resulting in good strength but requiring subsequent aging treatment. AMS 5732, on the other hand, includes an additional age hardening treatment (typically at 1325°F/720°C) on top of the AMS 5731 process, making it suitable for high-performance aerospace/turbine applications.
AMS 5732 vs AMS 5737
AMS 5732 and AMS 5737 both specify A286 stainless steel but differ in their heat treatment, leading to different strength levels: AMS 5737 is solution treated at a lower temperature (1650°F) and aged for higher strength (140 ksi tensile), while AMS 5732 is solution treated at a higher temperature (1800°F) and aged for slightly lower strength (130 ksi tensile) but potentially better high-temp performance/creep, with AMS 5732 essentially superseding older AMS 5735.
A-286 material achieves high strength after cold working and aging treatment, and is widely used in high-temperature fasteners and springs. We stock A286 steel in round bars (conforming to AMS 5731, 5732, and 5737 standards), plates, and coils (conforming to AMS 5525 and 5858 standards), and offer a variety of cutting and processing services.
