Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your reliable partner for high-quality stainless steel products. Our 304L Stainless Steel Rod 8mm, 12mm, 16mm, 20mm is a premium TIG welding grade round bar, meticulously manufactured to meet the demanding requirements of industrial fabrication and welding applications. With a dedicated commitment to quality and traceability, each rod is supplied with a Mill Test Report (MTR) ensuring full material compliance and consistency. Backed by our ISO9001-certified production system, these rods offer excellent corrosion resistance, weldability, and dimensional accuracy, making them an ideal choice for critical projects.
Our 304L stainless steel round bars are specifically designed for TIG welding processes, delivering smooth, clean welds with minimal post-weld treatment. The low carbon content of 304L (max 0.03%) reduces the risk of carbide precipitation during welding, maintaining superior corrosion resistance in heat-affected zones. Available in popular diameters of 8mm, 12mm, 16mm, and 20mm, these rods are suitable for a wide range of applications including structural supports, shafts, fittings, and custom machined parts.
- Superior Weldability – Low carbon composition ensures excellent TIG welding performance without sensitization.
- Full Traceability – Every rod is accompanied by a Mill Test Report showing chemical composition and mechanical properties.
- Precision Dimensions – Manufactured to tight tolerances (h9/h11) for consistent fit and finish.
- Corrosion Resistance – Ideal for use in marine, chemical, and food processing environments.
- Versatile Applications – Suitable for shafts, fasteners, valve components, and general fabrication.
- Custom Lengths Available – Standard 6m bars or cut-to-length options upon request.
