Daxun Alloys is proud to be a leading supplier of stainless steel tubing, adept at meeting diverse pipe demands. Type 304 stainless steel is an austenitic nickel alloy with an exceptionally low carbon content, making it perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy boasts remarkable strength, oxidation resistance, superb formability, and moderate machinability. For applications requiring enhanced resistance to intergranular corrosion, Daxun recommends 304L stainless steel, which offers superior immunity in highly corrosive environments. Our 304 stainless steel pipes are available in both seamless and welded forms and come in a variety of diameters. We also provide precision pipe cutting services to ensure your pipes are the exact length needed. Specializing in stainless steel pipes, Daxun invites you to contact us today.
Stainless Steel Welded Tubes
Our stainless steel tubular products, crafted from stainless steel strips, are expertly roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process ensures high integrity without the use of any filler metal.
Daxun is committed to delivering 304 stainless steel pipe products with exceptional speed and punctuality. This efficiency is backed by a robust system that integrates production capacity, information flow, logistics, and capital flow. For instance, Daxun's real-time order data seamlessly syncs with our logistics system. Our strategically located processing centers near ports, rivers, and seas ensure swift scheduling, rapid response, efficient storage, and transportation linkage. This meticulous orchestration guarantees the timely completion of tasks.
Stainless Steel Drawn TubeOur stainless steel tubular products are rolled and subsequently re-drawn to their final size. This rolling and drawing process is perfect for producing thick-walled, large-diameter tubes that can't be rolled directly to size, offering considerable cost savings over seamless tubes. Every drawn tube undergoes bright annealing for superior quality.
Daxun Advantages
