Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, proficient in addressing diverse pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy with exceptionally low carbon content, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, it boasts remarkable strength, oxidation resistance, superior formability, and moderate machinability. For heightened resistance to intergranular corrosion in harsh environments, we recommend our 304L stainless steel. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms, spanning a vast range of diameters. Additionally, we provide precise pipe cutting services to ensure your products meet your exact specifications. Specializing in stainless steel pipes, Daxun invites you to connect with us today.

Premium Stainless Steel Welded Tubes

Our stainless steel tubular products, derived from stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. The advanced welding methods employed by Daxun eliminate the need for any filler metal during the welding process, ensuring superior quality and durability.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products. This speed is bolstered by our comprehensive systems, spanning production capacity, information flow, logistics, and capital flow. For instance, our real-time order data is seamlessly integrated into the logistics system. Strategically located processing centers near ports, rivers, and seas enable efficient scheduling, rapid responses, and effective storage and transportation, ensuring timely completion of all tasks.

 

High-Quality Stainless Steel Drawn Tubes

Our stainless steel tubular products undergo rolling and subsequent re-drawing to achieve their final size. This method is ideal for creating thick-walled, large-diameter tubes that cannot be rolled directly but offer significant cost savings compared to stainless steel seamless tubes. All our stainless steel drawn tubes are bright annealed to ensure superior quality.
