Zusammenfassung:	A method of implementing a heat treatment process for enhancing strength of a part is provided. The method includes applying, by a controller, a gas quenching process to enable a controlled operation for cooling the part wherein the part comprises a steel material wherein the controlled operation for cooling the part is a subsequent action in the heat treatment process applied after the steel material of the part has been heated to a critical temperature. Also, controlling, by the controller, the cooling of the steel material of the part in the gas quenching process by affecting of changes in a cooling rate over one or more increments of time for the cooling of the part that results in at least an increase in value of an Ultimate Tensile Strength (UTS) of the steel material in correspondence with a decrease in the cooling rate by the controller.
