17-7 PH Stainless Steel

17-7 PH stainless steel  is a precipitation hardened stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and minimum distortion upon heat treatment. In high-heat treated conditions, 17-7PH stainless steel possesses excellent mechanical properties. 
The alloy provides valuable property combinations parcularly well suited for aerospace applications. This special alloy also provides benefits for other applications requiring high strength and good corrosion resistance - with excellent properties at temperatures up to 600° F.

Precision Steel  Warehouse carries 17-7 PH Stainless Steel in Condition A and Condition C. 17-7 Stainless Steel requires 3 steps in heat treating including austenite conditioning, cooling to transform the austenite to martensite, and precipitation hardening (for Condition TH & RH).
