Rotational bending fatigue tests for low alloy steels, KSFA80, KSFA110 were carried out to investigate the properties of the fatigue strength of high tensile forged materials. Fatigue fractures which started at an interior inclusion occurred even though the repeated stress exceeded 10^8 cycles. The fatigue strength of forged materials showed anisotropy depending on the relative direction of the specimen to forged fiber flow, and it is shown that this anisotropy of fatigue strength is due to the projective shape and size of inclusions at the crack origin to a plain perpendicular to the maximum stress direction. The effect of non-metallic inclusions on fatigue strength was estimated using the √ area parameter model.
