Exaton 2209LSi
2209LSi is designed for gas shielded arc welding and particularly MIG welding of duplex stainless steels, such as 2205 and 2304. Its corrosion resistance is equal to ASTM 904L in most applications. It combines high strength with excellent ductility. 2209LSi can also be used for joining 2205 or 2304 to carbon steel or low-alloy steels. It is used for MIG/MAG welding.
