Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at fulfilling a multitude of pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy renowned for its ultra-low carbon content, excels in welding applications. Known as '18/8' stainless steel owing to its 18% chromium and 8% nickel composition, it combines impressive strength, oxidation resistance, remarkable formability, and moderate machinability. For those needing superior resistance to intergranular corrosion, our 304L stainless steel is the optimal solution, offering heightened protection in harsh conditions. We provide 304 stainless steel pipes in both seamless and welded forms, featuring a diverse range of diameters to meet various needs. Additionally, our pipe cutting services ensure your products are tailored to precise lengths. Specializing in stainless steel pipes, Daxun Alloys is your go-to contact for unparalleled quality and service.

Stainless Steel Welded Tubes

Our stainless steel tubular products, meticulously crafted from stainless steel strips, are roll-formed and fusion-welded along the longitudinal seam. Notably, Daxun's advanced welding techniques eliminate the need for any filler metal, ensuring superior quality and durability.

Daxun guarantees prompt and reliable delivery of 304 stainless steel pipe products. This efficiency is backed by a robust system encompassing production capacity, information flow, logistics, and capital management. For instance, our seamless integration of order data with the logistics system ensures real-time updates. Strategically located near ports, rivers, and seas, our processing centers boast efficient scheduling, rapid response, and coordinated storage and transportation, guaranteeing timely delivery.

 

Stainless Steel Drawn Tube

Our stainless steel tubular products, initially rolled, are then re-drawn to achieve the final size. This rolling and drawing process is perfect for producing thick-walled, large-diameter tubes that cannot be rolled directly to size, offering cost efficiencies over seamless tubes. All drawn tubes are bright annealed for superior finish and quality.
