Time and temperature represent the main factors which determine the hardness profile on nitrided steels with certain composition. The upper limits in industrial applied nitriding temperatures usually range between 550 and 600°C. The application of nitriding in steps of rising temperature is demonstrated for the aluminium alloyed steel 34CrAlNi7. Thereby a surface hardness of 1000 HV 0,5 could be achieved at temperatures well above 600°C in substantially reduced nitriding time. The influence of the aluminium nitride precipitation as explanation for this behaviour is discussed.
