Tempering is done immediately after quenching to relieve quenching-stresses, at a temperature 425-600°C for 1 h plus 1 h per 25 mm thickness. Tempered hardness, tensile strength, yield strength, % elongation depend on as-quenched value, alloy content, tempering temperature, time at this temperature.
