Detailed Photos

Daxun Alloys proudly stands as a premier supplier of stainless steel tubing, adept at satisfying a diverse array of pipe requirements. Our Type 304 stainless steel is a meticulously crafted austenitic nickel alloy with low carbon content, making it perfect for welding projects. Known as "18/8" stainless steel due to its 18% chromium and 8% nickel composition, this alloy offers exceptional strength, oxidation resistance, superb formability, and moderate machinability. For applications demanding heightened resistance to intergranular corrosion, we recommend 304L stainless steel, renowned for its enhanced immunity in highly corrosive environments. Daxun Alloys provides 304 stainless steel pipes in both seamless and welded forms, available in a variety of diameters. Additionally, we offer precise pipe cutting services to meet your exact length specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to contact for unmatched quality and service.

Stainless Steel Welded Tubes

Our stainless steel tubular products are skillfully roll-formed and fusion-welded from stainless steel strips along the longitudinal seam. Daxun's advanced welding technique excludes the use of any filler metal, ensuring a seamless and robust end product.

Daxun ensures the prompt and efficient delivery of 304 stainless steel pipe products. This speed is backed by a robust system encompassing production capacity, information flow, logistics, and capital flow.
