Carbonitriding is a thermochemical process of hardening or surface carburizing carried out at temperatures from 850 to 900°C with the addition of ammonia gas to the furnace atmosphere. Carbonitriding is also considered to be a form of heat treatment that reduces distortion and can provide excellent hardness for different types of steel and even iron. The advantages of carbonitriding are the following:

  • increase in wear resistance
  • increase in the capacity of surfaces to withstand specific pressures of medium intensity
  • increase in fatigue resistance
