Daxun Alloys takes pride in being a top supplier of stainless steel tubing capable of meeting a wide range of pipe demands. Type 304 stainless steel is an austenitic nickel alloy with extremely low carbon content, making it ideal for welding applications. It is essentially an austenitic chromium alloy, sometimes known as "18/8" stainless steel because it contains 18% chromium and 8% nickel. Our 304 stainless steel pipe boasts exceptional strength, outstanding oxidation resistance, superb formability, and moderate machinability. For environments requiring enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, which offers superior immunity in extremely corrosive conditions. Daxun Alloys provides 304 stainless steel pipe in seamless or welded forms and a wide range of diameters. We also offer precise pipe cutting services to match your exact length specifications. Specializing in stainless steel pipes, contact Daxun Alloys today.
Stainless Steel Welded Tubes
Our stainless steel tubular products, crafted from stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process excludes any filler metal, ensuring the highest quality bonds.
Daxun guarantees timely and swift delivery of 304 stainless steel pipe products. Our rapid service is supported by an integrated system encompassing production capacity, information flow, logistics, and capital flow. Order data is instantly transmitted to our logistics system, ensuring seamless integration. Strategically located processing centers near ports, rivers, and seas facilitate efficient scheduling, rapid response times, and effective storage and transportation coordination, assuring that all tasks are completed punctually.
Stainless Steel Drawn TubeOur stainless steel tubular products undergo rolling followed by re-drawing to achieve their final size. This process is ideal for manufacturing thick-walled, large-diameter tubes that can't be directly rolled to size, offering cost advantages over seamless tubes. All our stainless steel drawn tubes are bright annealed for superior quality.
Daxun Advantages
