12 Heat Treatment Processes: Annealing, Normalizing 25crmnsi quenching and tempering steel

Purpose of hardening and tempering of knife steel Hardening is a way of making the knife steel harder. By first heating the knife steel to between 1050 and 1090°C (1922 and 1994°F) and then quickly cooling (quenching) it, the knife steel will become much harder, but also more brittle.12 Heat Treatment Processes: Annealing, Normalizing 25crmnsi quenching and tempering steel05 Quenching and tempering.
