Gas Nitriding or Nitrocarburizing are low temperature surface treatments to improve strength, gliding properties, wear resistance, temperature resistance and fatigue strength under reversed bending stresses. The process is carried out in a temperature range of 500-580°C. In a cracked ammonia atmosphere, either with or without carbon, nitrogen diffuses into the parts. Because the temperature is low there will be no transformation of the steel resulting in less distortion than e.g. with carburizing or carbonitriding. Very often parts do not need to be post machined as distortion is very little.
