Daxun is a distinguished global manufacturer of SS 17-4PH/630 Round Bar/Rod. As a prominent supplier and reputable distributor, we provide high-quality bars and rods to meet your needs.
We offer our customers a wide range of bars and rods with various parameters including surface treatments, end finishes, dimensions, shapes, and sizes to cater to diverse requirements.
SS 17-4PH is a remarkable martensitic stainless steel, hardened by precipitation. This alloy includes elements like nickel, copper, and chromium, making it ideal for aerospace fasteners and structural components. UNS S17400 undergoes a remelting process to achieve a microstructure that enhances its toughness.
Stainless Steel 17-4 PH Round Bar is highly favored in manufacturing and engineering due to its outstanding corrosion resistance, high strength, and production ease. 'PH' stands for Precipitation Hardening-a heat treatment process that significantly enhances the material's mechanical properties.
