Nickel Based Alloy
ES Ni 2 A5.11: ENiCrMo-5 / EN 14700: E Ni 2
Description
ES N2 Rutile basic covered, ~ 180% efficiency electrode. The weld metal to thermal shock, corrosion and abrasion resistant and extremely hard red is high. Improperly calm and spatter-free. Before using the electrodes must be dried for 2 hours to 200-250 °C.

Applications
It is outstandingly suitable for buildings on hot work tools (dies and jaws in forging machines, hot punches, forming dies, hot shear blades) requiring high red hardness and resistance to thermal shock. Particularly suitable for reconditioning to worn hot mandrels in pipe fabrication. Deposit does not require preheating but depends upon base metal.
