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.
Forming capabilities include state-of-the art extrusion and cold working assets for manufacturing tube and pipe products, one of the world's largest pilger mills, and a unique hydroforming processes to manufacture fittings.
As a vertically integrated manufacturer, we offer a one-stop shop and we have the ability to handle anything, whether it's an entire project or just a machining job.Straightening,Drilling,Honing,Trepanning,Cutting,Testing,Boring,Machining,Laser Weld,Polishing,Turning,Specialized Services.
With vertical and horizontal presses ranging from 12,000 tons to 35,000 tons, Daxun has the most comprehensive pipe extrusion capabilities in the world. Capabilities enable us to manufacture the longest lengths and largest diameter pipes in the industry.
Daxun supplies the power generation market with ductwork, boiler tubes, main steam tubes, thermal reheat tubes, flue gas desulfurization units and other products for nuclear, coal-fired, renewable energy and combined cycle applications.
