We offer both standard and custom sizes to satisfy the demanding needs of the aerospace, defense, chemical, and manufacturing sectors across the United States.
Stainless Steel 17-4 PH Hex Bars and Rods are martensitic precipitation-hardening alloys made up of about 15–17.5% chromium, 3–5% nickel, 3–5% copper, along with trace amounts of niobium and manganese, with iron as the base. This alloy boasts impressive mechanical strength and corrosion resistance, especially after undergoing heat treatment. It can achieve tensile strength up to 1310 MPa and yield strength around 1170 MPa, depending on its condition. Plus, it maintains toughness across a wide range of temperatures. Its ability to be hardened through heat treatment with minimal distortion makes it perfect for precision and high-load applications.
