2205 Duplex Stainless Steel Tube
Characteristics: High resistance to chloride stress corrosion cracking; Resistance to chloride pitting and crevice corrosion; Good general corrosion resistance; Good sulfide stress corrosion resistance; High Strength; Good weldability and workability.
2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.
The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 Stainless Tube, UNS S31803 Tube,uns S32205 Pipe to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.
