Detailed Photos

Daxun Alloys is a premier supplier of stainless steel tubing, adept at fulfilling a diverse array of pipe needs. Crafted from Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, our pipes are perfect for welding applications. Known as '18/8' stainless steel, this alloy boasts 18% chromium and 8% nickel, providing remarkable strength, oxidation resistance, superior formability, and moderate machinability. For heightened resistance to intergranular corrosion, we recommend 304L stainless steel, ideal for harsh environments. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms across a variety of diameters. Additionally, we offer precision pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to partner; contact us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products are expertly roll-formed and fusion-welded along the longitudinal seam, utilizing stainless steel strip. Daxun's advanced welding process eschews the use of any filler metal, ensuring superior quality and consistency.

Daxun ensures swift and timely delivery of 304 stainless steel pipe products, backed by robust systems from production capacity to logistics and capital flow. Our order data is seamlessly integrated in real time with our logistics system. Strategically located near ports and waterways, our processing center guarantees efficient scheduling, rapid response, adept storage, and swift transportation, ensuring on-time completion of tasks.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and subsequent re-drawing to achieve their final size. This method is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering cost advantages over seamless tubes. All our drawn tubes are bright annealed for enhanced quality.

Daxun Advantages

• Varieties: We offer a vast range of stainless steel pipes, from small to large diameters, in materials such as 304L, 316L, and others.
