<p>In a method for producing machine elements of steel having a carbon content of 0.3 to 1.1%, blanks are heated to austenitizing temperature and austenitized, quenched for the formation of martensite, heated from room temperature to a maximum tempering temperature, and immediately after reaching said maximum temperature cooled to room temperature to attain a hardness of 45 to 65 RHC and finish-machined to machine elements.</p> |
