Daxun Alloys takes pride in being a top supplier of stainless steel tubing capable of meeting a wide range of pipe demands. Type 304 stainless steel is an austenitic nickel alloy with extremely low carbon content, making it ideal for welding applications. It is essentially an austenitic chromium alloy, sometimes known as “18/8” stainless steel because it contains 18% chromium and 8% nickel. Our 304 stainless steel pipe has exceptional strength and oxidation resistance, great formability, and moderate machinability. For applications requiring increased resistance to intergranular corrosion, we propose 304L stainless steel, which has a better immunity in severely corrosive situations. Daxun Alloys carries 304 stainless steel pipe in seamless or welded form. 304 grade pipe is offered in a range of diameters. We also provide pipe cutting services to ensure that your pipe products are the exact length you require. Daxun specialises in stainless steel pipes; contact us immediately.
