Detailed Photos

Daxun Alloys is proud to be a leading supplier of high-quality stainless steel tubing, meeting diverse piping needs with unparalleled precision. Our Type 304 stainless steel is an austenitic nickel alloy with ultra-low carbon content, perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, it boasts remarkable strength, oxidation resistance, superior formability, and moderate machinability. For enhanced resistance to intergranular corrosion in harsh environments, we recommend 304L stainless steel. At Daxun Alloys, we offer 304 stainless steel pipes in both seamless and welded forms and a variety of diameters. Additionally, we provide precise pipe cutting services to ensure your products meet exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to partner.

Stainless Steel Welded Tubes

Daxun's stainless steel tubular products are crafted from high-quality stainless steel strips, roll-formed and fusion-welded along the longitudinal seam using a filler-free welding process. This high-precision method ensures durability and reliability.
