EN10088-1 Precipitation Hardening Steel 17-7PH/631 Stainless Steel Nickel Alloy Cold Drawn Bar
1 . Descriptions:
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 particularly 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 Aand 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).
