Aug 09, 2019Quenching is a rapid way of bringing metal back to room temperature after heat treatment to prevent the cooling process from dramatically changing the metal's microstructure. Metalworkers do this by placing the hot metal into a liquid or sometimes forced air. The choice of liquid or the forced air is referred to as the medium.(pipe) What do you need to know about hardening steel?What do you need to know about hardening steel?After hardening, you may need to temper the metal to remove some of the brittleness.
