AMS 5525 / A286 Stainless Steel Sheet

AMS 5525 is a sub-type specification of Stainless Steel A286. Alloy A286 is an iron-based, nickel-chromium austenitic stainless steel sheet product that is precipitation-hardened. The alloy should be considered for applications where a combination of high corrosion resistance and strength is required. The alloy possesses many favorable properties, including high strength at elevated temperatures, excellent corrosion resistance up to 1300 °F (700 °C), good fabrication properties, and low-temperature non-magnetic strength.

 

The AMS 5525 specification is solution heat-treated at 1800 °F (980 °C), followed by oil quenching, and holding for 16 hours at 1325 °F (720 °C).

 

Thanks to the excellent strength at elevated temperatures, AMS 5525 parts find use in various applications, including aircraft jet engine components, fasteners and springs in high-temperature environments, and industrial gas turbines.

 

Moreover, the corrosion resistance makes it useful in aqueous solutions with moderate corrosion properties (acetic acid, nitric acid, and salt spray). Ultimately, AMS 5525 can also be utilized for non-magnetic cryogenic parts, thanks to its excellent low-temperature strength, down to -320 °F (-196 °C).
