製品概要
Our Stainless Steel Round Bar (also known as stainless steel round rod or solid shaft) is manufactured from premium stainless steel billets through hot rolling, cold drawing, peeling, or precision grinding processes. With excellent corrosion resistance, high strength, and smooth surface finish, stainless round bars are widely used in shafts, ファスナー, machinery components, 工事, and general engineering. We supply a comprehensive range of stainless steel round bars in 304, 304L, 316, 316L, 321, 310S, 410, 420, 430, 17-4PH, and duplex grades, with custom diameters and surface finishes available.
