It is used for hard facing of alloyed and unalloyed steels. Worn surfaces of rails and ,rail surfaces, crane and conveyor wheels, cast steel valve seats, pinions, track rollers and links of earth mowing equipment can be hard faced with it, It is can also be used for joining of low carbon steels having % 13 Cr. It is recommended to use ES 55 R in multi pass applications as it is a basic coated electrode. It is also recommended to have a preheating and inter pass temperature of minimum 200°C. Hardening in oil or air at 980°C - 1000°C, Softening in furnace at 780°C - 800°C.
