Daxun is an internationally renowned manufacturer of SS 17-4PH/630 Round Bar/Rod. We proudly supply, export, and distribute high-quality bars and rods to meet global standards.
We offer an extensive range of bars and rods, customizable in surface treatment, end finish, dimensions, shapes, and sizes, to meet every client's specific needs.
SS 17-4PH is a martensitic stainless steel that gains its strength through precipitation hardening. This alloy benefits from the addition of nickel, copper, and chromium. Widely utilized in the aerospace sector, it is ideal for fasteners and other structural components. Known as UNS S17400, it features a microstructure improved during the remelting process, thereby enhancing its toughness.
Stainless Steel 17-4 PH Round Bar is a versatile and highly sought-after material within the manufacturing and engineering sectors. It is celebrated for its outstanding corrosion resistance, robust strength, and effortless machinability. The 'PH' in 17-4 PH stands for Precipitation Hardening, a heat treatment process that significantly enhances the material's mechanical properties.
