Detailed Photos

Daxun Alloys takes immense pride in being a leading supplier of stainless steel tubing, adept at fulfilling a broad spectrum of pipe requirements. Our Type 304 stainless steel is an austenitic nickel alloy, renowned for its exceedingly low carbon content, making it the premier choice for welding applications. Known colloquially as '18/8' stainless steel for its 18% chromium and 8% nickel composition, this austenitic chromium alloy stands out for its remarkable strength, excellent oxidation resistance, superb formability, and moderate machinability. For cases requiring superior resistance to intergranular corrosion, we recommend the 304L variant, designed for the most corrosive environments. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms, available in a wide array of diameters. Additionally, our pipe cutting services guarantee precise lengths tailored to your needs. Specializing in stainless steel pipes, Daxun Alloys is your go-to partner - contact us today!

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from high-quality stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. The advanced welding process employed by Daxun ensures that no filler metal is used, maintaining the integrity and purity of the material.

Daxun guarantees timely and swift delivery of 304 stainless steel pipe products. This efficiency is underpinned by our robust systems, encompassing production capacity, seamless information flow, logistics, and capital flow. Our real-time order data integration with the logistics system ensures seamless connectivity. Strategically located processing centers near ports, rivers, and seas enable optimal scheduling, rapid response, and efficient storage and transportation, ensuring on-time task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and then re-drawing to achieve final size specifications. This method 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 stainless steel drawn tubes are bright annealed, ensuring superior quality.

Daxun Advantages
