Daxun is a premier global manufacturer of SS 17-4PH/630 Round Bar/Rod. As a trusted supplier, exporter, and distributor, we deliver high-quality bars and rods that meet the industry's demanding standards.
We offer an extensive range of bars and rods, customizable by various parameters including surface treatment, end finish, dimensions, shapes, and sizes to meet diverse customer needs.
SS 17-4PH is a martensitic stainless steel that achieves its hardness through a precipitation hardening process. This alloy, enriched with nickel, copper, and chromium, is predominantly employed in the aerospace industry for fasteners and structural components. The UNS S17400 microstructure, refined during the remelting process, significantly enhances the alloy's toughness.
Stainless steel 17-4 PH Round Bar is highly sought after in manufacturing and engineering due to its superior corrosion resistance, high strength, and production ease. The 'PH' signifies precipitation hardening, a heat treatment process that optimizes the material's mechanical properties.
