Quenching and tempering are heat treatment processes used to improve the mechanical properties of certain types of steel. These processes are typically performed sequentially, with quenching followed by tempering.
Quenching is a rapid cooling process used to harden steel.
It involves heating the steel to a high temperature, typically above the critical transformation temperature, and then rapidly cooling it by immersing it in a quenching medium such as oil, water, or a polymer solution.
The rapid cooling rate prevents the formation of larger crystals in the steel structure, resulting in a hardened and brittle material.
