17-7 PH (AMS 5528)

17-7PH precipitation hardening stainless steel offers a combination of attractive properties that make the alloy particularly suitable for aerospace engineering applications. 17-7PH provides high strength and hardness with good corrosion resistance and good formability. Other attractive characteristics include excellent fatigue resistance and minimal distortion when heat treated. The corrosion resistance of the alloy is generally superior to most hardenable stainless steel though this superiority depends on particular delivery conditions. 17-7PH precipitation hardening alloy may be formed in a soft austenitic condition and hardened to a high strength level by low-temperature heat treatments.

Commercial Applications

Typical applications include aerospace, chemical processing and oil refinery components.
