Daxun Alloys is proud to be a premier supplier of stainless steel tubing, adept at fulfilling a wide spectrum of pipe requirements. Type 304 stainless steel, an austenitic nickel alloy with minimal carbon, is perfect for welding applications. Known as '18/8' stainless steel due to its 18% chromium and 8% nickel content, this alloy boasts exceptional strength, oxidation resistance, superb formability, and moderate machinability. For heightened 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, across various diameters, and provide pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to source. Contact us today.

Stainless Steel Welded Tubes

Our stainless steel tubular products, crafted from stainless steel strips, are roll-formed and longitudinally fusion-welded. Daxun's welding process is unique as it doesn't involve any filler metal, ensuring purity and strength.

Daxun ensures swift and reliable delivery of 304 stainless steel pipe products, supported by a robust production capacity, real-time information flow, efficient logistics, and strong capital flow. For instance, our order data integrates seamlessly with our logistics system in real-time. Strategically located near ports, rivers, and seas, our processing centers offer quick response, efficient scheduling, storage, transport linkage, and timely loading, guaranteeing on-schedule task completion.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products undergo rolling and re-drawing to achieve final sizing. This process is perfect for producing thick-walled, large-diameter tubes that can't be directly rolled to size but provide cost benefits over seamless tubes. All our drawn tubes are bright annealed for superior quality.

Daxun Advantages

• Varieties: From small to large diameter, our stainless steel pipes range across sizes and grades, including 304L, 316L, and more.
• Flexibility: Whether you require seamless or welded pipes, our range can cater to your specific project needs.

• Custom Orders: Need special sizes? We offer various customization options for stainless steel pipes at competitive prices with convenient online ordering.

 

Stainless Steel Seamless Tube

Our stainless steel seamless tubes are crafted from hollow sections created through piercing or hot extrusion. Ideal for large diameter to wall thickness ratios, they offer excellent external dimensional tolerances.

Quality, delivery, inspection

• At Daxun, we perform multiple quality assurance tests including flattening, pitting resistance, mechanical, hardness, material positive identification, and expansion tests. These ensure our materials meet application requirements.
• Throughout production, we measure the diameter, thickness, and surface of each product. Standard delivery is 7-15 days; special sizes may extend to 20 days.
  Our delivery times strictly adhere to contractual agreements.
• We support customer third-party agency inspections at our factory.
• We offer free samples to customers for testing.
