4. tempering: tempering is the quenching or ignition after casting heating to Ac, below a selected temperature, insulation after a certain time, at the appropriate rate of cooling, make the quenching or ignition after unstable tissue into stable organization, eliminate quenching (or ignition) stress and improve the plasticity and toughness of cast steel a heat treatment process. Usually the process of quenching and high temperature tempering treatment is called quality adjustment treatment. The quenching steel casting must be tempered in time, and the hot steel casting must be tempered when necessary. The performance of the steel casting after tempering depends on the tempering temperature, time and times. With the increase of the tempering temperature and the extension of the time, in addition to eliminating the quenching stress of the steel casting Partes, quod inconstans est Martensense convertitur in tempering martensite, firmamentum et Sotensite, ita quod fortitudo et duritia et in malle, et tungsten, et etc. {VI}}), quod est in Phaenomenon, et exaltatibus et in VI, et in Tungsten Diplino D gradus decrementum ad CD ~ D gradus dicitur secundarium, id est, quod duritiam mittendi ferro in tempering statum ad maximum valore, {{IX}} Plerumque, quod medium est temperari (I ~ III temporibus) {{XII}

(2) High temperature tempering: the high temperature tempering temperature is 500~650℃, and cooled after appropriate insulation time. It is mainly used for the organization of cast steel after quenching or regular ignition, so that it has high strength and good toughness of carbon steel and low and medium alloy steel casting.
