AMS 5860 is an aerospace material specification for a corrosion resistant precipitation
hardenable stainless steel alloy. Common names for the alloy are Custom 455, Alloy 455, or
UNS S45500.
AMS 5860 includes material in the form of sheet, strip, and plate.
This alloy is typically used where a combination of high strength and corrosion resistance is
required in applications with service temperatures up to 800 deg F.
Material is premium quality with vacuum melting and consumable electrode remelting required.
It is supplied in the solution heat treated condition.
To assure the results of the final precipitation hardening treatment of component parts; samples
of the product are precipitation hardened and tensile tested for conformance to specification
minimum strength requirements. For more info on 455 click here.
