Technological treatment processes Possible application Temperature, °C
Hot forming Forging + 850 – 1100
Rolling + 850 – 1100
Thermochemical treatment Carburising + 880 – 950
Carbonitriding + 860 – 930
Heat treatment Annealing Normalising + 870 – 900
Soft annealing + 650 – 700
Heat treatment after carburising1) Core hardening + 840 – 870
Intermediate annealing + 630 – 650
Case hardening + 800 – 830
Tempering + 170 – 200
1) If possible, hardening has to be performed with the temperature equal or close to the heat treatment temperature
