15-5 stainless steel is a precipitation-hardening, corrosion resistant, martensitic steel that shows good mechanical properties at temperatures up to 600° F. 15-5 is capable of high hardness and strength after a simple heat treat. 15-5PH has high strength and good toughness in all directions as a base stainless steel and in welding applications.

15-5 stainless steel can be heat treated at low temperatures for a short time to minimize scaling and distortion. 15-5 when vacuum arc remelted improves cleanliness. 15-5ph is martensitic and magnetic in both PH (precipitation hardened) and solution treated conditions.

When 15-5 is precipitation hardened in a single low temp range from 900° – 1150° scaling and distortion are practically eliminated. That enables 15-5ph to be machine finished to close tolerances before heat treatment.

15-5 stainless steel is extremely resistant to a wide variety of corrosion. When hardened at temps of 1000° and higher 15-5 is highly resistant to stress corrosion cracking. 15-5PH can be heat treated at low temperatures for a short time to minimize scaling and distortion. 15-5 when vacuum arc remelted improves cleanliness. 15-5 is martensitic and magnetic in both PH (precipitation hardened) and solution treated conditions.
