Grade: 17-7PH
Formula: Fe/Cr 17/Ni 7
Form: Coil
Material: Stainless Steel
Commodity: Alloys
17-7PH Stainless Steel Coil is a precipitation-hardened martensitic stainless steel offering an exceptional balance of high tensile strength, corrosion resistance, and thermal stability. Its composition allows for enhanced hardness through aging treatments, while maintaining ductility for forming and fabrication. This coil format is widely used in aerospace, petrochemical, and precision engineering sectors, where strong yet lightweight corrosion-resistant materials are essential. Applications include spring components in aircraft control systems, precision diaphragms in petrochemical instrumentation, and high-resilience fasteners in mechanical assemblies. In research and innovation, 17-7PH stainless steel coil supports advanced prototyping for fatigue-resistant components, development of corrosion-resistant high-load structures, and integration into thermal and chemical testing platforms. Its combination of performance, formability, and reliability ensures continued value in both demanding industrial operations and cutting-edge scientific applications.
