Daxun Alloys is proud to be your premier supplier of stainless steel tubing, meeting an extensive array of 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 composition, it boasts exceptional strength, oxidation resistance, formability, and moderate machinability. For applications that require enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, renowned for its superior performance in harsh environments. At Daxun Alloys, our 304 stainless steel pipes are available in seamless or welded forms, in a variety of diameters. Additionally, we offer precise pipe cutting services to ensure your products meet exact length specifications. Trust Daxun for your stainless steel pipe needs; contact us today.

Premium Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strips, are roll-formed and fusion-welded along the longitudinal seam. Daxun's state-of-the-art welding process does not utilize any filler metal, ensuring seamless quality.

Daxun guarantees prompt and efficient delivery of 304 stainless steel pipe products. Our streamlined process is supported by robust systems spanning production capacity, information flow, logistics, and capital flow. For instance, our real-time data integration ensures seamless connectivity between order data and the logistics system. Strategically located processing centers near ports, rivers, and seas enable optimized scheduling and rapid response, ensuring efficient storage, transportation, and on-time task completion.

 

Precision Stainless Steel Drawn Tubes

Our stainless steel tubular products are rolled and then precisely re-drawn to their final size. This rolling and drawing process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering significant cost savings over seamless tubes. All our drawn tubes undergo a bright annealing process for superior quality.
