Stainless Steel 17-7 PH Bars and Rods are a precipitation-hardening stainless steel alloy made up of roughly 17% chromium and 7% nickel, along with some copper, aluminum, and iron to balance the composition. This unique blend results in high strength, impressive corrosion resistance, and solid toughness. In terms of mechanical properties, they showcase a tensile strength between 1,100 and 1,400 MPa, a minimum yield strength of 930 MPa, and an elongation of about 10–15%. The alloy remains stable at higher temperatures and offers outstanding fatigue resistance, making it perfect for critical applications that require both mechanical strength and corrosion resistance.
