Abstract: The paper presents results regarding cooling intensities of some oils of domestic production and of polymeric water solutions (PWSs). Knowledge of quenching agents in terms of cooling intensity and knowledge of physical phenomena in the boundary layer permit improvement of monitoring and technology of heat treatment. Temperature measurements on heat-treatment steel specimens were made. They provided very important information on cooling rates for a material when using different quenching agents. In heating and subsequent quenching of blanks/workpieces, it is very important that internal stresses of workpieces are always lower than yield stress of the material at a given temperature in order to avoid deformation of the workpiece.
