Daxun Alloys is proud to be a premier supplier of stainless steel tubing, expertly fulfilling diverse pipe demands. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel content, this alloy offers outstanding strength, oxidation resistance, excellent formability, and moderate machinability. For superior resistance to intergranular corrosion in highly corrosive environments, we recommend our 304L stainless steel. Daxun Alloys provides 304 stainless steel pipes in both seamless and welded forms, available in various diameters, and offers precision pipe cutting services to meet exact length requirements. As specialists in stainless steel pipes, we invite you to contact Daxun Alloys today.

Stainless Steel Welded Tubes

Our stainless steel tubular products are masterfully crafted from stainless steel strips, roll-formed and fusion-welded along the longitudinal seam. Notably, Daxun's welding process is uniquely effective as it excludes the use of any filler metal.

Daxun ensures the prompt and efficient delivery of 304 stainless steel pipe products. This speed is underpinned by robust systemic support spanning production capacity, information flow, logistics, and capital flow. For instance, Daxun's order data is transmitted in real-time to the logistics system, ensuring seamless data integration. Strategically located near ports and major waterways, our processing centers offer optimal scheduling, swift response, coordinated storage and transportation, and efficient loading, guaranteeing your orders are fulfilled punctually.

 

Stainless Steel Drawn Tube

Stainless steel tubular products are meticulously rolled and then re-drawn to the final size. This rolling and drawing process is ideal for creating thick-walled, large-diameter tubes that cannot be directly rolled to size, yet still provides cost savings compared to stainless steel seamless tubes. All our stainless steel drawn tubes undergo bright annealing for superior quality.

Daxun Advantages

• Varieties: We offer an extensive range of sizes and grades of stainless steel pipes, from small to large diameters, including 304L, 316L, and more.
• Flexibility: Whether your project demands seamless or welded steel pipes, our stainless steel pipes are designed to meet your specific requirements.
