Louis Metals stands out as a top manufacturer and supplier of Stainless Steel 17-7 PH Hex Bars and Rods, proudly based in Houston, USA. We’re known for our unwavering commitment to quality, precision, and reliability, providing high-performance stainless steel products that are engineered for the toughest applications. Our 17-7 PH hex bars and rods boast impressive strength, hardness, and corrosion resistance, making them perfect for industries like aerospace, chemical processing, and mechanical engineering. With our advanced manufacturing capabilities and a customer-centric approach, Louis Metals delivers customized stainless steel solutions that meet strict specifications and tight tolerances for both standard and bespoke industrial needs across the United States.
Stainless Steel 17-7 PH Hex Bars and Rods are made from precipitation-hardened alloys primarily consisting of iron, along with 16–18% chromium, 6.5–7.75% nickel, and 0.75–1.5% aluminum. This unique blend gives the alloy remarkable mechanical properties and excellent corrosion resistance. It can achieve a tensile strength of up to 1300 MPa and a yield strength of around 1100 MPa, depending on the heat treatment process. The alloy also offers good fatigue strength, minimal distortion during heat treatment, and retains high strength in both extreme heat and cold. These characteristics make it a go-to choice for applications that demand high mechanical performance and dimensional stability.
