duplex 2205

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.

Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength. Grade S31803 stainless steel was modified several times to form UNS S32205, which was recognized in 1996. This grade has higher corrosion resistance.

 

Duplex 2205 pipe is a popular choice for various industrial applications, including chemical processing, oil and gas, marine, and many others. It’s a reliable and cost-effective option for transporting fluids or gases in corrosive environments.

 

Although duplex 2205 pipe is more expensive than traditional stainless steel, it is relatively cheaper than high nickel alloys or other corrosion-resistant alloys. Therefore, it is a cost-effective choice for applications that require superior corrosion resistance, high strength, and durability.

 

Duplex 2205 pipe can be used for a range of applications, which include transporting chemicals, gases, and liquids in chemical plants, refineries, and offshore platforms. Additionally, it is easy to weld and fabricate, making it suitable for various manufacturing processes. Duplex 2205 pipe can be easily cut and shaped to fit specific requirements. This aspect is especially important as it allows for customization according to the specific requirements of a particular application.
