Technical data: Strength Rm [N/mm2]: 450 Hardness: 160-190 HB Electrode type (cover): alkaline-graphite Drying: 180°C / 1 h Universal electrode with a bimetal Ni-Fe core designed for cold welding of all types of cast iron (ductile, grey, malleable) and for joining cast iron with steel. For welding cast iron with the highest strength. Very good for making the first layers in combinations with cast iron. Excellent welding performance, does not overheat during welding. Very small splash, easy slag to come off, fine-husked fillings. High strength alloy, resistant to cracking. The weld is fully machinable. It can be welded AC Uo APPLICATION: Machine and motor bodies Regeneration and welding of valves Welding of cast iron with steel ** Illustrative photos.
