Precipitation Hardening Stainless Steel

Precipitation Hardening stainless steels, or hardenable chromium-nickel alloys, are classified as martensitic or semi-austenitic. They develop their high strength and hardness through a variety of heat treatments. They are used in aircraft parts and commonly viewed as bar alloys, but are also available in flat roll products with a very high strength-to-weight ratio. The martensitic steels are used in aerospace, chemical and petrochemical, and food processing applications. Semi-austenitic grades are 17-7 and PH 15-7. They are austenitic in the annealed state, but martensitic in the hardened condition. Other grades of PH alloy stainless steels include 17-4 and 15-5. These grades achieve high tensile properties in heat treated conditions.

Typical Applications
Aerospace Components, Flat Springs and Retaining Rings, among many other uses.
