Used in the 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°C and 1090°C (1922 and 1994°F) and then quickly cooling (quenching) it, the knife steel will become much harder, but also more brittle. Tempering at temperatures between 100°C and 500°C reduces the brittleness of the steel and improves toughness.
