Stainless Steel 17-4 PH Hex Bars and Rods are prized for their remarkable strength, hardness, and resistance to corrosion, making them perfect for tough engineering tasks. As a precipitation-hardening stainless steel, 17-4 PH boasts impressive mechanical properties whether it’s in its annealed or heat-treated state. The hexagonal design not only improves machinability but also ensures stability and precision during fabrication, making these bars and rods ideal for creating high-accuracy components. Their ability to maintain strength even at high temperatures, along with dependable toughness and dimensional stability, makes them a go-to choice in industries like aerospace, petrochemical, marine, and high-performance manufacturing.
These hex bars and rods are made with key elements like chromium, nickel, and copper, which allow for precipitation hardening through heat treatment. They deliver outstanding tensile strength ranging from 930 to 1310 MPa and yield strength between 860 and 1100 MPa, depending on the specific condition (H900–H1150). The alloy also offers good corrosion resistance similar to that of 304 stainless steel in many settings, while excelling in hardness and fatigue strength. With a high strength-to-weight ratio, excellent wear resistance, and stability under thermal and mechanical stress, they are perfect for critical load-bearing applications.
