W = Width, THK = Thickness, L = Length, ρ = Density
What is 17-7PH Stainless Steel
17-7PH, also known as stainless steel grade 631, stands out as a precipitation hardening alloy designed for demanding engineering environments. Its composition features chromium, nickel, and aluminum, which enable precipitation hardening and deliver high strength with excellent corrosion resistance. Stainless steel grade 17-7 ph achieves tensile yield strengths comparable to other advanced steels, reaching up to 1,730 MPa. The presence of chromium above 11% and nickel above 8% ensures corrosion resistance, while aluminum supports precipitation hardening. This steel excels in fatigue resistance and workability, making it essential in aerospace, medical, and high-performance engineering applications. Grade 17-7PH stainless steel provides a unique balance of high strength and corrosion resistance, supporting critical applications that require reliable properties and consistent performance.
