Introduction about hardening and tempering

Hardening → Heating work piece to a certain temperature.Cooling rapidly at water, oil, or other inorganic salts, organic aqueous solution etc. quenching medium. After quenching,steel work piece getting hard , but also brittle. 
Tempering → In order to reduce the brittleness of the steel, make the hardened heat preservation, a suitable temperature, higher than room temperature and lower than 710 ℃ , and then cooling.This process is called tempering.

 

In order to obtain a certain degree of strength and toughness, sometimes combine quenching and tempering process,called quenched and tempered.
