OK Autrod 347

OK Autrod 347 is suitable for joining stainless steels of the 18Cr/8Ni/Nb and 18Cr/8Ni/Ti types. Due to the strenghtening effect of niobium, this grade is recommended if the weld metal will be exposed to temperatures above 400°C (750°F). It is used for joining and overlay welding with MIG/MAG, plasma and hot wire TIG and mechanized TIG.
