Duplex Stainless Pipe Suppliers Corrosion Resistance

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 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 and Citizen Metals has been actively involved in ensuring the best quality of the same to our clients. 

This exotic alloy is used in oil and gas exploration, chemical processing industries also make use of this alloy. Most of the processing equipment utilizes Duplex 2205. It is also used by storage and transportation units of industries. Pulp and paper digesters, liquor tanks and paper machines also use Duplex 2205. It is highly suitable for usage in marine environments.
