Detailed Photos

Daxun Alloys stands as a venerable supplier of top-tier stainless steel tubing, adeptly catering to diverse pipe demands. Our Type 304 stainless steel, celebrated for its austenitic nickel alloy composition, boasts an ultra-low carbon content, making it the premium choice for welding applications. Often referred to as '18/8' stainless steel, it comprises 18% chromium and 8% nickel. The 304 stainless steel pipe we offer demonstrates superior strength, exceptional oxidation resistance, remarkable formability, and moderate machinability. For enhanced resistance to intergranular corrosion, we recommend our 304L stainless steel, specially designed to excel in highly corrosive environments. Daxun Alloys provides both seamless and welded 304 stainless steel pipes in various diameters, along with precision cutting services to meet custom length requirements. Specializing in stainless steel pipes, we invite you to contact us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products are expertly roll-formed and fusion-welded from premium stainless steel strips. The longitudinal seam welding process at Daxun is meticulously executed without the use of any filler metal, ensuring impeccable quality.

At Daxun, we pride ourselves on the prompt and efficient delivery of our 304 stainless steel pipe products. This rapid service is backed by a robust system encompassing production capacity, seamless information flow, logistics, and financial management.
