Nitrocarburizing is one of the prominent surface treatment methods for steels. The effects of ferritic nitro carburizing on En-19, En-24 and En-37 steels are compared. Microstructural investigations of FNC treated samples are carried out. Micro hardness profiles of FNC treated steels are drawn. Further wear investigations are carried out. It is observed that FNC treated En-19 steel has more wear resistance in comparison to En-24 and En-37 steels.
