2205 Duplex Stainless Steel Pipe Supplier – High Strength Corrosion-Resistant Tubing for Industrial Applications
2026/08/05
2205 duplex stainless steel pipe (UNS S32205/S31803) has become the material of choice for engineers and procurement managers worldwide, and for good reason. This dual-phase alloy — composed of approximately 50% austenite and 50% ferrite — delivers a unique combination of high mechanical strength and exceptional corrosion resistance that outperforms conventional austenitic grades like 304L and 316L in demanding environments.
At Zhongcheng Metal. we supply premium 2205 duplex stainless steel pipes manufactured in strict compliance with ASTM A789, ASTM A790, ASME SA789/SA790, and EN 10216-5 standards. Our comprehensive inventory covers a wide dimensional range to serve diverse industrial requirements across global markets.
