Located in the heart of Hamilton, New Zealand, Blundell Pipes and Tubes is a trusted name for industrial-grade materials, bringing reliable solutions to demanding projects. We are proud to supply Stainless Steel 17-7 PH Pipes, a product chosen by engineers who need more than standard stainless can offer. This alloy is renowned for its unique ability to be heat-treated to achieve impressive strength, making it an ideal choice for applications where high performance and excellent corrosion resistance are absolutely non-negotiable.
The strength of 17-7 PH Stainless Steel comes from its careful composition, primarily chromium and nickel, with a crucial addition of aluminum. This specific blend allows it to undergo a hardening treatment that significantly boosts its mechanical properties. After this process, these pipes achieve remarkably high tensile and yield strength, offering a level of durability that stands up to heavy loads and stressful environments, all while maintaining good flexibility and toughness to resist impact.
