Abstract (en)
[origin: WO2012141639A1] Method for heat treating a steel component (28, 36) to provide the steel component (28, 36) with a surface having improved wear resistance. The method comprises the steps of carbonitriding the steel component (28, 36) at a temperature of 930-970°C, cooling the steel component (28, 36), re-heating the steel component (28, 36) to a temperature of 780-820°C and either quenching the steel component (28, 36) to form martensite and tempering, or quenching the steel component (28, 36) to form bainite and tempering.
