A286 Stainless Steel Bar - AMS 5726, AMS 5731, AMS 5732

Typical Applications

Fasteners

Stud Bolts

Industrial Gas Turbines

A286 is a precipitation hardenable alloy.

High nickel and chromium content gives it a good resistance to corrosion up to about 1300 Deg C and Oxidation up to about 1500 Deg F. A286 (UNS S66286) can be age hardened to a high strength level. The alloy is also used for low temperature applications requiring a ductile, non-magnetic high strength material at temperatures ranging from above room temperature down to at least -320 Deg F. The alloy (AMS 5726, AMS 5731, AMS 5732, AMS 5737) may be used for moderate corrosion applications in aqueous solutions.
