Bare corrosion resisting chromium nickel welding rod for welding of similar steels of 24% Cr, 13% Ni types. The alloy is also used for welding of buffer layers on CMn steels and welding of dissimilar joints. When using the wire for buffer layers and dissimilar joints it is necessary to control the dilution of the weld. OK TIGROD® 309L has a good general corrosion resistance. When used for joining dissimilar materials the corrosion resistance is of secondary importance.
