Duplex 2205 Flanges

Duplex 2205 Flanges are also known for their socket weld flanges and are usually used for small high pressure piping system. The raw material used is of high quality and is installed by welding around the hub of the flanges.

Key Benefits:

Good general corrosion resistance

High resistance to chloride stress corrosion cracking, as well as pitting and crevice corrosion

Good sulfide stress corrosion resistance

High strength and good fatigue resistance

Good weldability and workability

High energy absorption

Low thermal expansion

Product Details

duplex 2205 flanges

Duplex 2205 flanges are made from an austenitic-ferritic stainless steel, which was once designed to supply greater power and corrosion resistance than 300 sequence stainless steels. It helps customers to keep away from stress corrosion cracking that is normally viewed with 316 and 317. Duplex 2205 flanges mix the features of stress corrosion cracking resistance and excessive electricity derived from being a ferritic alloy alongside with its austenitic fabrication capabilities.
