Detailed Photos

Daxun Alloys prides itself as a premier supplier, adept at fulfilling a diverse array of stainless steel pipe requirements. Distinguished by its extremely low carbon content, Type 304 stainless steel is an austenitic nickel alloy perfect for welding applications. Known colloquially as the '18/8' stainless steel due to its 18% chromium and 8% nickel composition, this alloy boasts exceptional strength, outstanding oxidation resistance, and excellent formability with moderate machinability. For environments demanding superior resistance to intergranular corrosion, our 304L stainless steel variant offers enhanced durability. Available in both seamless and welded forms, our 304-grade pipes come in a wide variety of diameters. We also provide precision pipe-cutting services to match your exact specifications. Specializing in stainless steel pipes, Daxun Alloys invites you to contact us immediately to experience unparalleled quality and service.

Superior Stainless Steel Welded Tubes

Crafted from roll-formed stainless steel strips, our welded tubular products undergo longitudinal seam fusion welding, devoid of any filler metals. Daxun's specialized welding technique ensures unmatched integrity and robustness in every tube.

Daxun ensures prompt and efficient delivery of 304 stainless steel pipes, backed by a robust system encompassing production capacity, seamless information flow, and optimized logistics. For instance, our order data is instantly relayed to the logistics system, ensuring flawless coordination. Our processing centers, strategically located near ports and waterways, guarantee swift logistical responses, synchronized storage, and efficient loading, ensuring timely completion of every task.

 

Precision Stainless Steel Drawn Tube

Our stainless steel tubular products are meticulously rolled and re-drawn to achieve the final size. This rolling and drawing method is ideal for producing thick-walled, large-diameter tubes that cannot be directly sized through rolling alone, offering significant cost advantages over seamless tubes. Each drawn tube undergoes bright annealing for superior finish and quality.
