Stainless Steel 17-7 PH is a precipitation-hardened alloy made of chromium, nickel, and aluminum. Typically, it contains 17% chromium, 7% nickel, and a small percentage of aluminum (0.75–1.5%) to enhance hardening. This alloy strikes a perfect balance between impressive strength, moderate corrosion resistance, and excellent fatigue properties. The 17-7 PH Tubing boasts a tensile strength of up to 1400 MPa and a yield strength of about 1200 MPa in the TH 1050 condition. It shows minimal distortion during heat treatment, offers great formability when annealed, and maintains high strength after hardening. This makes it ideal for demanding applications that require both strength and precise dimensions under repeated stress.
