Properties And Applications

High recovery (120%), austenitic manganese steel electrode for hardfacing and joining of high manganese steels. Due to it excellent impact resistance, particularly suited for parts which are subjected to heavy impact, shock and cavitation. The addition of Ni and Cr alloys, increases the resistance against cracks and abrasion. Weld metal work hardens by cold-working. During welding, the workpieces should not become too hot and it shall be cool down, when necessary. High welding currents and wide-weave beads must be avoided. Machining is possible with tungsten carbide tipped tools. Suitable for hardfacing and repair welding of dredge pumps, hydraulic press pistons, crane wheels, rail crossings, crusher jaws, excavator and grab teeth, mill hammers, rock crusher.
