Nakamura Stainless, based in Pulau Ujong, Singapore, is a reputable manufacturer and supplier of top-notch stainless steel materials designed to meet the needs of industries worldwide. One of their standout products is the Stainless Steel 17-7 PH Bars, known for their remarkable precipitation-hardening capabilities, exceptional corrosion resistance, and impressive tensile strength. These bars are crafted for critical applications, ensuring outstanding durability and dimensional stability even in varying conditions. With cutting-edge manufacturing techniques, rigorous quality controls, and timely delivery, Nakamura Stainless provides 17-7 PH bars that cater to the aerospace, marine, chemical, and power sectors, all while adhering to international standards for reliable performance in challenging environments.
Stainless Steel 17-7 PH Bars are made up of chromium (16–18%), nickel (6.5–7.75%), and aluminum (0.75–1.5%), which give them remarkable precipitation-hardening traits and oxidation resistance. After undergoing heat treatment, these bars can achieve tensile strengths of up to 1100 MPa while still maintaining good ductility and hardness. They also boast excellent fatigue strength, wear resistance, and dimensional stability under stress and temperature changes. The alloy’s well-balanced composition allows for fabrication in an annealed state, followed by hardening to deliver superior mechanical properties for demanding industrial and engineering applications.
