摘要
The present invention is directed to a method for producing steel components such as gears and/or shafts of superior bending fatigue strength and pitting fatigue life. According to the present invention said components are made from a steel material , comprising 0.10 to 0.30 weight%Carbon,0.15 to 0.35 weight%Silicon,0.3 to 1.5 weight%Chromium,0.30 to 2.0 weight%Nickel,0.08 to 0.50 weight%Molybdenum,0.6 to 1.5 weight%Manganese,0.017 to 0.040 weight%Aluminium and balance iron including impurities, produced in vacuum degassing and alike routes.wherein these components are subjected to a method comprising in sequence the steps ofsubjecting said steel components to a process of modified Carbonitriding treatment, andsubjecting said steel components to a process of Hard Shot Peening.
