Stainless Steel 17-7 PH Fasteners consist of roughly 17% chromium and 7% nickel, along with a small percentage of aluminum to allow precipitation hardening. The alloy is prized for its superior mechanical strength, fatigue life, and satisfactory corrosion resistance in most industrial conditions. The fasteners have tensile strengths of up to 1300 MPa and yield strengths of approximately 1100 MPa, varying with the heat treatment. They have good mechanical properties over a broad range of temperatures and provide high performance under heavy stress and cyclic loading conditions, making them suitable for challenging structural and mechanical applications.
