Abstract (en)
[origin: WO2005108629A1] The invention relates to a method for the gas quenching of steel parts having undergone thermochemical treatment, which is performed with a cooling gas stream which is obtained by introducing the liquid phase thereof into a gas quenching chamber (2). The cooling gas comprises water vapour which is obtained by evaporating water introduced into the chamber (2) in liquid form. The inventive method can also comprise the introduction of a first gas before the introduction of the water in liquid form.
