Daxun Alloys takes immense pride in being a premier supplier of stainless steel tubing, adept at fulfilling diverse pipe requirements. Our Type 304 stainless steel, an austenitic nickel alloy with ultra-low carbon content, is perfect for welding applications. Known also as "18/8" stainless steel, it boasts 18% chromium and 8% nickel, ensuring remarkable strength and oxidation resistance. This grade offers superior formability and moderate machinability. For heightened resistance to intergranular corrosion, especially in highly corrosive environments, we recommend our 304L stainless steel variant. Available in seamless or welded forms, our 304 stainless steel pipes come in a variety of diameters. We also offer precise pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun Alloys is your go-to provider. Contact us today.

Stainless Steel Welded Tubes

Crafted from stainless steel strip, our stainless steel tubular products are roll-formed and fusion-welded along the longitudinal seam. Unique to Daxun, our welding technique employs no filler metals, ensuring seamless integrity.
