Abstract

For producing a forging with good fatigue strength the billet for the desired forging is made of a material which, in addition to iron, contains the following elements: C from 0.2 to 0.6 percent by weight Si from 1.25 to 2.0 percent by weight Mn from 0.5 to 1.5 percent by weight V from 0.04 to 0.2 percent by weight S from 0 to 0.2 percent by weight Cr from 0 to 0.5 percent by weight Al from 0 to 0.1 percent by weight N from 0 to 0.04 percent by weight Nb from 0 to 0.1 percent by weight Ti from 0 to 0.05 percent by weight. The billet is forged at a temperature of more than 800 DEG C. Subsequently, the billet, which has now become a forging, is cooled in air or gas substantially uniformly acting on the forging.
