Detailed Photos

Daxun Alloys is your trusted supplier of premium stainless steel tubing designed to meet diverse piping needs. The Type 304 stainless steel we offer is an austenitic nickel alloy with low carbon content, perfect for welding applications. Known as '18/8' stainless steel, it contains 18% chromium and 8% nickel, combining outstanding strength with excellent oxidation resistance, remarkable formability, and moderate machinability. For applications that demand higher resistance to intergranular corrosion, consider our 304L stainless steel, which excels in highly corrosive environments. Available in both seamless and welded forms, our 304 grade pipes come in various diameters. We also provide precise pipe cutting services to ensure the exact length you require. Specializing in stainless steel pipes, Daxun Alloys is ready to assist you.

Stainless Steel Welded Tubes

Our stainless steel tubular products are crafted from stainless steel strips, roll-formed and fusion-welded along the longitudinal seam. Daxun's innovative welding process ensures no filler metal is used, maintaining the integrity and purity of the welded tubes.

Experience timely and efficient delivery of 304 stainless steel pipe products with Daxun. Our robust system supports this speed, from production capacity and information flow to logistics and capital flow. For instance, our order data seamlessly integrates with the logistics system in real-time. Strategically located processing centers near ports, rivers, and seas enable quick responses and efficient loading, ensuring timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and redrawing to achieve final size. This process is ideal for producing thick-walled, large-diameter tubes that are cost-effective compared to seamless tubes. All our stainless steel drawn tubes undergo bright annealing to ensure superior quality.
