The hardening cycle starts with heating from room temperature to the required hardening temperature ( A = austenitizing) of between 1050 and 1090°C (1922 and 1994°F), depending on the steel grade. The material is then quenched ( Q = quench) to room temperature in the space of less than 2 minutes, possibly followed by deep-freezing ( DF = deep-freezing) to between 20 and -70°C (-4 and -94°F). Heat Treating Knives :7 Steps - InstructablesHeat Treating Knives:The purpose of heat treating is to bring steel to a hardened state. The correct hardness depends on the application of the steel being treated. Knives need to be hard enough to hold an sharp edge through continuous mechanical abrasion, yet be soft

Heat Treatment- Annealing, Normalizing, Hardening

Hardening is a heat treatment process carried out to increase the hardness of Steel. It consists of heating Steel components to the temperature within or above its critical range. Held at this temperature for a considerable time to ensure thorough penetration of heat at this temperature well inside the component and then allowed to cool Heat Treatment- Annealing, Normalizing, Hardening Hardening is a heat treatment process carried out to increase the hardness of Steel. It consists of heating Steel components to the temperature within or above its critical range.

Heat treating a knife blade Heat treat and tempering

Heat treatment refers to the process where softer steel is hardened so that it stands up to use as a knife blade. To heat treat steel, I heat it up beyond cherry red to glowing red. For 1095 steel (as this blade is), this occurs at a temperature above 1335° F. High Speed Steel 440C Tool Steel 440C SteelHardening and Tempering. 440C can be hardened for maximum hardness by oil quenching or air cooling from 1850 to 1900°F. Large sections or complex parts should be preheated to 1425°F, equalize, and then raised to the austenitizing temperature.

Hardening and tempering of knife steel Sandvik Materials

To reduce the brittleness, the material is tempered, usually by heating it to 175350°C (347662°F) for 2 hours, which results in a hardness of 5363 HRC and a good balance between sharpness retention, grindability and toughness. Tempering should be carried out within a reasonable time after hardening, preferably within an hour or so.
