Austenitic stainless steel MMA-electrode giving a weld metal of the CrNiMn-type. The weld metal, which contains a small amount of uniformly distributed ferrite, is tough and has an excellent crack resistance. Suitable for joining 13%Mn-steels and such steels to other steels. Also suitable for welding of other steels with very poor weldability.
