Daxun stands as a globally recognized manufacturer of SS 17-4PH/630 Round Bar/Rod. We pride ourselves on being a reliable supplier, exporter, and esteemed distributor of premium quality bars and rods.
We provide our customers with an extensive selection of bars and rods, tailored to various specifications such as surface treatment, end finish, dimensions, shapes, and sizes.
SS 17-4PH is a martensitic stainless steel, enhanced by precipitation hardening. It incorporates alloying elements like nickel, copper, and chromium. Renowned in the aerospace industry, this alloy is used for fasteners and structural components. UNS S17400's microstructure, refined in the remelting process, significantly boosts its toughness.
Stainless Steel 17-4 PH Round Bar is celebrated for its exceptional corrosion resistance, superior strength, and manufacturing versatility. The 'PH' denotes precipitation hardening, a heat treatment process that augments the material's mechanical properties.
