At Jiangsu Daxun Alloy Co., Ltd., we proudly stand as industry leaders in stainless steel tubing, adept at fulfilling diverse pipe requirements. Our 304 stainless steel, an austenitic nickel alloy with low carbon content, is perfect for welding applications. Known as "18/8" stainless steel for its 18% chromium and 8% nickel composition, it offers remarkable strength, oxidation resistance, and exceptional formability. For environments demanding enhanced resistance to intergranular corrosion, we recommend our 304L stainless steel, famed for its superior durability in harsh conditions. Whether you need seamless or welded 304 stainless steel pipes, available in various diameters, Daxun Alloys ensures precision with our pipe cutting services. Specializing in stainless steel pipes, we invite you to contact us for unparalleled quality and service.

Stainless Steel Welded Tubes

Our stainless steel tubular products, made from stainless steel strips, are meticulously roll-formed and fusion-welded along the longitudinal seam. Daxun's welding process stands out by not requiring any filler metal, ensuring the highest integrity and strength in our welded tubes.

Jiangsu Daxun Alloy Co., Ltd. guarantees timely and efficient delivery of 304 stainless steel pipes backed by robust systems.
