Daxun Alloys proudly stands as a leading supplier of stainless steel tubing, designed to meet diverse pipe demands. Our Type 304 stainless steel, an austenitic nickel alloy with a remarkably low carbon content, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, it offers exceptional strength, oxidation resistance, excellent formability, and moderate machinability. For superior resistance to intergranular corrosion in highly corrosive environments, we recommend 304L stainless steel. Available in seamless or welded forms and various diameters, our 304-grade pipes can be cut to your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to source. Contact us today!

Premium Stainless Steel Welded Tubes

Our stainless steel tubular products are meticulously roll-formed and fusion-welded along the longitudinal seam from stainless steel strips. The advanced welding process used by Daxun ensures no filler metal is utilized, guaranteeing superior quality.

Daxun ensures prompt and efficient delivery of 304 stainless steel pipe products. Our system supports seamless integration from production capacity, information flow, logistics, to capital flow. For instance, our order data is instantly pushed to the logistics system for real-time updates. Strategically located processing centers near ports and waterways facilitate quick response times, efficient scheduling, and streamlined storage and transportation, ensuring timely task completion.

 

Exquisite Stainless Steel Drawn Tubes

Our stainless steel tubular products are first rolled and then re-drawn to their final size. This process is perfect for manufacturing thick-walled, large-diameter tubes that cannot be rolled directly while still offering cost savings compared to stainless steel seamless tubes. All our stainless steel drawn tubes undergo a bright annealing process for impeccable quality.

Distinct Daxun Advantages
