Known for their precision engineering and cutting-edge manufacturing techniques, the company is committed to upholding global standards, ensuring that every product they offer delivers remarkable performance and reliability. The Stainless Steel 17-7 PH Hex Bars and Rods from Phehlukwayo Metal are highly regarded for their exceptional strength, resistance to corrosion, and impressive hardness, making them perfect for demanding environments that experience high stress and temperatures across various industries.
The Stainless Steel 17-7 PH Hex Bar/Rod is a precipitation-hardening stainless steel alloy, primarily made up of iron, 17% chromium, 7% nickel, along with trace amounts of aluminum. This unique blend results in a fantastic mix of strength, ductility, and corrosion resistance. After undergoing heat treatment, the alloy can achieve tensile strength levels of up to 1250 MPa and yield strength around 1070 MPa, along with excellent resistance to fatigue and creep. It also maintains solid mechanical stability at temperatures reaching up to 600°F (315°C) and boasts great forming and welding characteristics when in its annealed state.
