FW 2209 is a solid wire for TIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. It gives radiographic quality weld deposit. Deposits have duplex microstructures consisting of an austenite - ferrite matrix, which is characterized by high tensile strength, resistance to stress corrosion cracking, and improved resistance to pitting. It is used primarily to weld duplex stainless steels, which contain approximately 22 percent Cr such as UNS S31803 and S32205.
