OK 67.45
Austenitic stainless steel electrode giving a weld metal with less than 5 % ferrite. The tough weld metal has an excellent crack resistance, also when welding steels with very poor weldability. Suitable for joining 12 to 14 % manganese steel with itself or other steels. Also suitable for buffer layers before hard facing.
