Daxun Alloys takes immense pride in being a premier supplier of stainless steel tubing tailored to meet diverse pipe requirements. Type 304 stainless steel is an extraordinary austenitic nickel alloy with ultra-low carbon content, making it exceptionally suitable for welding applications. It is primarily an austenitic chromium alloy, often referred to as "18/8" stainless steel due to its 18% chromium and 8% nickel composition. Our 304 stainless steel pipe stands out with its remarkable strength, superior oxidation resistance, excellent formability, and moderate machinability. For applications necessitating an enhanced resistance to intergranular corrosion, we recommend 304L stainless steel, renowned for its superior immunity in highly corrosive environments. Daxun Alloys offers 304 stainless steel pipes in both seamless and welded forms, available in a spectrum of diameters. We also provide precision pipe cutting services to meet your exact specifications. Specializing in stainless steel pipes, Daxun is your go-to partner for all your stainless steel piping needs. Contact us today!
Stainless Steel Welded Tubes
Our stainless steel tubular products, crafted from high-quality stainless steel strips, are roll-formed and fusion-welded along their longitudinal seam. The state-of-the-art welding process employed by Daxun eliminates the need for any filler metal, ensuring superior structural integrity.
Daxun ensures prompt and rapid delivery of 304 stainless steel pipe products. This efficiency is backed by robust systems supporting production capacity, information flow, logistics, and financial management. For instance, our order data is instantly integrated into the logistics system, enabling seamless data connectivity. Strategically located near ports, rivers, and seas, our processing centers facilitate prompt, well-scheduled, and efficient logistics operations, ensuring timely task completion through rapid response, storage, transportation linkage, and proficient loading.
Stainless Steel Drawn TubeOur stainless steel tubular products are meticulously rolled and subsequently re-drawn to achieve their final dimensions. This rolling and drawing process is ideal for manufacturing thick-walled, large-diameter tubes that cannot be rolled directly to size, all while offering significant cost savings compared to stainless steel seamless tubes. Each drawn tube undergoes a bright annealing treatment for enhanced quality.
