15-5PH is a precipitation-hardening stainless steel conforming to AMS 5659 & AMS 5862.

---

15-5PH is a strong alloy benefitting from excellent transverse toughness.

Product Info:

The alloy is a derivative of 17-4PH stainless steel, offering attractive performance characteristics, including excellent transverse toughness and ductility from solution annealing and precipitation hardening - 15-5PH benefits from combined characteristics present in martensitic and austenitic material grades. Corrosion resistance is good and is comparable with the corrosion resistant performance of other austenitic stainless steels.

Heat treating 15-8PH:

The impressive mechanical properties of the alloy come to the forefront after heat treatment. Solution annealing is performed at temperatures ranging from 1010°C to 1150°C and subsequent precipitation hardening at 480°C. The resulting strength and toughness depend on the specific chosen temperature.

Workability & Machinability:

15-8PH precipitation-hardening stainless steel is often supplied in the solution-treated condition, making it readily machinable. The material also benefits from good workability, formability and weldability.
