Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at meeting diverse pipe demands. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, excels in welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, it offers remarkable strength, oxidation resistance, excellent formability, and moderate machinability. For applications requiring superior resistance to intergranular corrosion, our 304L stainless steel is ideal, providing enhanced immunity in highly corrosive environments. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms, available in a variety of diameters. We also provide precise pipe cutting services to meet your exact length requirements. Specializing in stainless steel pipes, Daxun Alloys is your trusted partner; contact us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strips, our tubular products are meticulously roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process ensures no filler metal is used, guaranteeing superior quality.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products, supported by a robust system from production capacity to logistics and capital flow. Our advanced information flow integrates real-time order data with our logistics system for seamless connectivity. Strategically located processing centers near ports, rivers, and seas ensure rapid response and efficient storage, transportation, and loading, ensuring timely task completion.

 

Stainless Steel Drawn Tube

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

Daxun Advantages
