Neesham Flanges, based in the industrial heart of Hamilton, New Zealand, is a trusted name for high-performance piping components. We take pride in supplying robust Stainless Steel 17-7 PH Flanges, engineered for demanding environments where standard materials fall short. Our focus is on delivering reliability straight from our local workshops to complex projects across the globe, ensuring each flange meets the precise standards required for critical applications. We understand that behind every component is a system that needs to perform flawlessly.
The strength of 17-7 PH Stainless Steel comes from its unique composition, which includes chromium and nickel, and a special precipitation hardening heat treatment. This process allows these flanges to be formed in a softer state and then hardened to achieve exceptional mechanical properties. The result is a material that offers an outstanding combination of high tensile strength and good corrosion resistance, making it significantly tougher than many common austenitic stainless grades without sacrificing durability.
