Detailed Photos

Daxun Alloys takes immense pride in being a premier supplier of stainless steel tubing, adept at fulfilling a vast array of pipe demands. Our Type 304 stainless steel, an austenitic nickel alloy with exceptionally low carbon content, is perfect for welding applications. Often referred to as '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy boasts remarkable strength, oxidation resistance, excellent formability, and moderate machinability. For enhanced resistance to intergranular corrosion, especially in highly corrosive environments, we recommend 304L stainless steel. At Daxun Alloys, we offer 304 stainless steel pipes in both seamless and welded forms, available in a wide range of diameters. Additionally, our pipe cutting services ensure your products are tailored to the exact lengths required. As specialists in stainless steel pipes, we invite you to contact us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products are expertly crafted from roll-formed and fusion-welded stainless steel strips, processed along the longitudinal seam. Daxun's sophisticated welding technique ensures no filler metal is used during the welding process, guaranteeing purity and strength.

Daxun ensures the prompt and efficient delivery of 304 stainless steel pipe products. Our streamlined system, from production capacity and information flow to logistics and capital flow, underpins this speed. For instance, our order data is seamlessly integrated with the logistics system in real time, ensuring smooth operations. Strategically located processing centers near ports, rivers, and seas facilitate swift scheduling, rapid response, and efficient loading, ensuring timely task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products are meticulously rolled and then re-drawn to achieve their final size. This rolling and drawing process is perfect for producing thick-walled, large-diameter tubes, offering significant cost savings compared to stainless steel seamless tubes. All our stainless steel drawn tubes undergo bright annealing for superior finish and quality.
