Duplex 2205 ( UNS S31803) is a nitrogen enhanced duplex stainless steel that is designed to combat common corrosion problems encountered with the SS316/SS304 stainless steel grades. Falcon Duplex 2205 stainless steel valves has good resistance to chloride pitting and crevice corrosion. This resistance is extremely important for services such asOffshore plants, desalination plants, brackish water, bleaching operations, chemical processing, oil and gas productions and some food processing applications.
Following type of Valves are manufactured by Falcon
Characteristics of duplex stainless steel
Duplex stainless steel has high strength and excellent ductility. It provide better resistance to pitting and crevice corrosion. Pitting resistance equivalent (PREN) range is 28-38.
