摘要：
Method for treating a crank pin of a crank shaft. In the method hardness of the crank pin surface is measured and when the hardness is over a predetermined limit value, depth of the hard spot is measured. Heat treatment parameters are determined at least on the basis of the depth measurement and the hard spot is heat treated. During the heat treatment the hard spot is heated by an induction heating device.
