E 7-UM-200-KP

Basic covered, austenitic manganese steel electrode for wear resisting hardfacing deposits on high manganese (12-14%) steels. Weld metal will adopt high hardness by cold-working, it is therefore particularly suited for parts which are subjected mainly to wear caused by heavy impact and shock. During welding, the workpieces should not become too hot and if necessary, be allowed to cool down. When welding large workpieces made of austenitic manganese steel, such as crusher jaw plates, it is advisable to weld them in a water bath. Welding shall be done at low welding currents, with stringer and short bead lengths, to avoid the workpiece cool down. So, high welding currents and wide-weave beads must be avoided. When building up various layers, it is good practice depositing a buffer layer with EI 307 weld metal. When making joint welds on austenitic manganese steel, it is preferable to use EI 307B electrodes. Suitable for hardfacing and repair welding of wear resisting parts made of austenitic manganese steel, such as crusher jaw plates, crusher cones, rolls, pulverizing hammers, beating arms and others. Preferably used with DC, electrode in positive (+) pole and also possible to use with AC.

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.

High recovery (140%), austenitic manganese steel electrode for joining and hardfacing of high manganese steels which are subjected to very high pressure, shocks and abrasion. It is suitable to use as a buffer layer prior to hardfacing. Due to it is 12% Cr content, weld metal has high crack resistance and abrasion resistance with respect to other manganese steel electrodes. Weld metal work hardens by cold-working. Workpiece shall not become too hot during welding and when necessary, it shall be cool down before next hardfacing passes. High welding currents and wide-weave beads must be avoided. When welding large workpieces made of austenitic manganese steels, it is advisable to weld them in a water bath. Suitable for hardfacing and repair welding of dredge pumps, hydraulic press pistons, crane wheels, rail crossings, crusher parts subjected to impact of soft minerals.
