A method of producing a forged steel part is disclosed. The method includes providing a steel billet that can be selectively hardened to different hardness levels by varying the air cooling rate. The method also includes heating the steel billet to an austenization temperature of the steel billet. The method further includes hot forging the steel billet to form the steel part including a first region and a second region. The method yet further includes selectively cooling the hot forged steel part by air cooling the first region at a first cooling rate and air cooling the second region at a second cooling rate that is less than the first cooling rate.
