PROGRESSO
Panoramica del prodotto
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, alta resistenza, and smooth surface finish, stainless round bars are widely used in shafts, elementi di fissaggio, machinery components, costruzione, 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.
