Quenching is the process of rapidly cooling material from high temperatures.
This rapid cooling is achieved using quenching media.
The thickness of the material to be quenched along with the rate of cooling required helps to choose the quenching medium.
The most widely used quenching media are:
- brine solution
- water
- oil
- air
Brine solution gives a faster rate of cooling while air cooling has the slowest rate of cooling.
Brine is a high-concentration solution of salt (NaCl) in water.
Order of rate of cooling is Brine > water > oil > air
