Stainless Steel Round Bar – CNC Machining Ready

Ruixiang Steel is a trusted global supplier of high-precision stainless steel round bar, engineered for CNC machining, shafts, fasteners, valves, and precision components across automotive, aerospace, food processing, and industrial equipment sectors. Our bars are manufactured to tight tolerances and delivered in grades that ensure excellent machinability, corrosion resistance, and mechanical strength.

We stock and produce cold-drawn and hot-rolled stainless steel round bars in diameters from 3mm to 300mm, with standard lengths of 2m, 3m, 4m, or 6m—custom cut-to-length available upon request. Available grades include AISI 304, 304L, 316, 316L, 410, 420, and 430, compliant with ASTM A276/A484, EN 10088-3, JIS G4303, and GB/T 1220 standards. Surface finishes range from peeled & polished to centerless ground, ensuring smoothness and dimensional accuracy ideal for automated machining.

As an ISO 9001-certified manufacturer and exporter based in Shandong, China—just hours from Qingdao Port—we implement rigorous quality control: ultrasonic testing, hardness verification, chemical composition analysis, and straightness inspection. Every shipment includes a Mill Test Certificate (EN 10204 3.1) with full traceability by heat number.

Our stainless round bars are free of surface defects, uniformly hardened, and optimized for high-speed CNC lathes, milling centers, and grinding operations—reducing tool wear and scrap rates. Whether you're producing pump shafts, surgical instruments, or food-grade fittings, Ruixiang Steel delivers material you can machine with confidence.

We support small-batch prototyping and bulk orders, with options for protective packaging, bar coding, and just-in-time delivery. With decades of metallurgical expertise and a customer-first approach, we serve precision engineers and distributors in Europe, North America, the Middle East, and Southeast Asia.
