An experimental study of quenching of boron steels, using polyalkyleneglycol (PAG) as quenching fluid, was developed. An experimental device for intense quenching was designed and built and the effect of PAG concentration in a low concentration range (2,4 and 6%vol.) was analyzed. The thermal histories of cylindrical steel probes instrumented with type K thermocouples were obtained. In addition, the heat transfer coefficients associated with the types and means of quenching used were obtained by solving the inverse problem of heat conduction. It was found that the cooling rate curves behave differently from those reported in conventional fluids and this effect is associated with the vapor layer and the polymer adhered to the metal surface.
