Daxun is a global manufacturer of SS 17-4PH/630 Round Bar/Rod range. We are a distinguished supplier, exporter, and reputable distributor of premium-quality bars and rods.
We offer our esteemed customers a diverse range of bars and rods, meticulously crafted with various parameters such as surface treatment, end finish, dimensions, shapes, and sizes.
SS 17-4PH is a martensitic stainless steel hardened by precipitation. The alloy incorporates nickel, copper, and chromium, making it indispensable in the aerospace sector for fasteners and structural components. UNS S17400's microstructure, refined during the remelting process, significantly enhances its toughness.
Stainless steel 17-4 PH Round Bar is a versatile and highly sought-after material in the manufacturing and engineering sectors, thanks to its superior corrosion resistance, remarkable strength, and ease of production. The 'PH' in 17-4 PH stands for precipitation hardening, a heat treatment process that significantly enhances the material's mechanical properties.
