Detailed Photos

At Daxun Alloys, we proudly stand at the forefront of stainless steel tubing suppliers, adeptly meeting diverse pipe demands. Our Type 304 stainless steel, an austenitic nickel alloy, boasts an ultra-low carbon content, making it perfect for welding applications. Known as '18/8' stainless steel for its 18% chromium and 8% nickel composition, it offers unmatched strength, oxidation resistance, exceptional formability, and moderate machinability. For projects demanding superior intergranular corrosion resistance, our 304L stainless steel is the ideal choice, especially in highly corrosive environments. Whether you need seamless or welded pipes, Daxun Alloys provides 304 stainless steel pipes in various diameters and offers precision pipe-cutting services to meet your exact specifications. As stainless steel pipe specialists, contact Daxun Alloys today for your next project.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. Unique to Daxun, our welding process is devoid of any filler metals, ensuring purity and integrity in every weld.

Daxun ensures prompt and efficient delivery of 304 stainless steel pipe products. Our speed is backed by a comprehensive system encompassing production capacity, information flow, logistics, and capital flow. For instance, our order data seamlessly integrates with the logistics system in real-time. Additionally, our strategically located processing centers near ports and waterways, coupled with efficient scheduling and rapid response mechanisms, guarantee timely completion of your orders.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling followed by re-drawing to achieve the final size. This rolling and drawing process is perfect for manufacturing thick-walled, large-diameter tubes that cannot be rolled directly to size, while still offering cost advantages over seamless tubes. Every stainless steel drawn tube is bright annealed to perfection.

Daxun Advantages

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