OK 67.43 is an austentitic, stainless steel, AC/DC electrode, which deposits a weld metal with a small amount of uniformly distributed ferrite. The tough weld metal has excellent crack resistance, even when welding steels with very poor weldability. Suitable for welding 13Mn steels and steels of this kind to other steels.
