How do you temper steel
WebHardening 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. To reduce the brittleness, the material is tempered, usually by heating it to 175–350°C (347–662°F ...
