China 2205 Duplex Stainless Steel Tubing Manufacturer

The standard of 2205 grade of steel has been refined over the years creating a versatile and strong product. The China 2205 Duplex Stainless Steel Tubing is one of the most widely used ferritic and austenitic duplex stainless steel pipes. China 2205 Duplex Stainless Steel Tubing combination of ferrite and austenite is the most beneficial properties, has a very good resistance to chloride stress corrosion cracking. It has an excellent corrosion resistance (including in seawater), it is weldable by all standard methods, and has high heat resistance.

  • S32205, 2205; S32750, 2507
  • X2CrNiMoN22-5-3, 1.4462; X2CrNiMoN25-7-4, 1.4410
  • Austenitic
  • cold drawn / cold rolled

Duplex Stainless Steel (DSS) including duplex 2205(S31803) and super duplex, commonly consists of 50% ferrite and 50% austenite and generally requires not less than 30%. China 2205 Duplex Stainless Steel Tubing has good welding performance and high strength. Compared with austenitic stainless steel, it is about double yield strength from stainless steel 316, 317, etc. It makes the equipment lighter and stronger. China 2205 Duplex Stainless Steel Tubing has very good resistance to localized corrosion and stress corrosion cracking. China 2205 Duplex Stainless Steel Tubing is not intended to be used at temperatures above 300°C due to embrittlement, the continuous use temperature is from -50 to 250 °C.


The specialty of China 2205 Duplex Stainless Steel Tubing is that it contains a dual nature. It is neither ferritic nor austenitic but contains the best of both parts. China 2205 Duplex Stainless Steel Tubing is an ideal choice for the applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. 


China 2205 Duplex Stainless Steel Tubing is our strong product. Duplex steel is an austenite-ferrite dual-phase stainless steel, it is developed for applications that demand high strength and corrosion resistance. China 2205 Duplex Stainless Steel Tubing is a cost-effective solution for many applications where the 300 series stainless steel pipe is susceptible to chloride stress corrosion cracking.
