AUTOTHERME-2209

AWS: SFA 5.9 ER2209

Autotherme-2209 is a solid wire for MIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. It gives radiographic weld quality 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 steel, which contain approximately 22%Cr such as UNS S31803 and S32205.
