Abstract: Method for heat treating a steel component (28, 36) comprising the steps of: a) carbonitriding the steel component (28, 36) at a temperature of 930-970°C, b) cooling the steel component (28, 36), d) re-heating the steel component (28, 36) to a temperature of 780-820°C and d) quenching the steel component (28, 36). The method comprises the step of holding the steel component (28, 36) at an initial temperature (T 1 ) above the initial martensite formation temperature (Ms), and lowering the initial temperature (T 1 ) to a temperature (T 2 ) that is below the initial martensite formation temperature (Ms) but above the actual martensite formation temperature during the bainite transformation.

Abstract: The present invention related to a method and an apparatus arrangement for determining a fatigue limit for rolling contact initiated fatigue of a rolling bearing. The method comprises running a rolling bearing while being exerted to a load which generates sub surface transformations in a rolling element contact zone of the outer or inner ring. Furthermore a set of sub surface transformations in the contact zone along a raceway portion of the rolling bearing is identified and measured and used for generation of a parameter data set wherein a fatigue parameter value representative of a predicted fatigue limit for the rolling bearing is determined based on the generated data set of sub surface transformations.
