E2209-16 duplex stainless steel electrodes are used to weld 22% chromium duplex stainless steel such as 2205, 2209, 2304 and other proprietary duplex stainless steels. It has a smooth running arc that deposits very high tensile strength, with resistance to stress, corrosion,
cracking and pitting. These all-position rods have easy strike and re-strike with spatter-free arc, self-releasing slag leaving a smooth bead appearance. E2209 may also be a good choice when welding Duplex stainless such as 2553 to carbon steels or other grades of stainless.
