Stainless Steel 15-5

Specs: ASTM-A-564, AMS 5659
UNS#: S15500

15-5 Stainless Steel is a martensitic, precipitation hardening, Chromium-Nickel-Copper Stainless Steel. The Stainless 15-5 alloy combines high strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with 304 stainless.


The general level of corrosion resistance is best in the fully hardened condition and decreases slightly as the aging temperature is increased. 15-5 Stainless may also be used in the solution treated condition or heat-treated to obtain a wide variety of properties.


This alloy is used in aerospace, aircraft components, fabricated parts in high- pressure corrosive environments including valves, shafts, fasteners, fittings, and gears.

Available shapes – round
