Quenching and Tempering

Quenching and Tempering is a heat treatment process which changes the state of martensite structure by heating steel with carbon content of 0.3% or more to the austenitizing temperature around 850oC and then rapidly cooled in water or oil. After that, tempering is usually performed for the purpose of providing toughness to the steel hardened by quenching.
