What is Quenching?

Quenching is a heat treatment process used to harden materials by rapidly cooling them down from a high temperature to room temperature. This process can be done in various mediums, such as water, oil, or air. Quenching can increase the strength and wear resistance of materials, making them more suitable for demanding applications.

When a material is heated to a high temperature and then rapidly cooled, its structure changes from a relatively soft and ductile state to a harder and more brittle state. The cooling rate, quenching medium, and temperature all affect the final properties of the material. For example, a material quenched in water will cool faster than one quenched in oil, resulting in a harder and more brittle material. Quenching is often used on steels and other ferrous alloys.
