Executive 2209 wire is designed to provide clean and consistent welds with excellent feedability and minimal clean-up. By maintaining tight control from the country of melt to the design of the spool Executive wire provides welders with the highest quality stainless bare wire. Corrosion-resistant electrode for the GMAW of austenitic-ferritic duplex stainless steels. Executive 2209 is a filler metal designed to weld duplex stainless steels which contain approximately 22 percent chromium. These alloys have "duplex" microstructures consisting of an austenite-ferrite matrix. Executive 2209 wire is lower in ferrite compared to that of the base metal in order to obtain improved weldability.
