Daxun Alloys takes immense pride in being a premier supplier of stainless steel tubing, engineered to cater to a myriad of pipe demands. Our Type 304 stainless steel is an austenitic nickel alloy with ultra-low carbon content, making it the ideal choice for welding applications. This alloy, commonly known as "18/8" stainless steel, contains 18% chromium and 8% nickel, conferring it with exceptional strength, oxidation resistance, superb formability, and moderate machinability. For applications demanding enhanced resistance to intergranular corrosion, we recommend our 304L stainless steel, which offers superior immunity in highly corrosive environments. At Daxun Alloys, we provide 304 stainless steel pipes in both seamless and welded forms, available in a wide range of diameters. Our precise pipe cutting services ensure that your pipe products meet your exact length requirements. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us today to fulfill all your pipe needs.
Stainless Steel Welded Tubes
Our stainless steel tubular products, made from high-quality stainless steel strips, are expertly roll-formed and fusion-welded along the longitudinal seam. Daxun's advanced welding process ensures no filler metal is used, guaranteeing optimal purity and strength of the weld.
Daxun ensures timely and rapid delivery of 304 stainless steel pipe products. Our unparalleled speed is backed by a robust system encompassing production capacity, real-time information flow, seamless logistics, and efficient capital management. For instance, our order data is instantly pushed to our logistics system, ensuring seamless data integration. Proximity to ports and rivers allows our processing center to execute reasonable scheduling, rapid response, coordinated storage, and transportation, ensuring task completion within deadlines.
Stainless Steel Drawn TubeOur stainless steel tubular products are precisely rolled and subsequently re-drawn to achieve the final size. This rolling and drawing process is perfect for manufacturing thick-walled, large-diameter tubes that cannot be directly rolled to size, while still providing cost savings over seamless tubes. Every drawn tube undergoes bright annealing for a flawless finish.
Daxun Advantages
