17-7 ALLOY STAINLESS STEEL

The 17-7 stainless steel grade is particularly well suited for high strength, corrosion resistant applications. It performs well at temperatures up to 600ºF. Fabrication processes are similar to other chromium-nickel stainless steels.
Product Information
Stainless Grade 17-7 PH  is a precipitation hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and minimum distortion upon heat treatment. The alloy provides valuable property combinations particularly well suited for aerospace applications. This special alloy also provides benefits for other applications requiring high strength and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 600°F (316°C).
