Half-Finished Technology of Steels and Fatigue Strength

Abstract

The paper presents the bending fatigue testing for four steel brands. The test showed that the fatigue strength is decreasing with the increasing of both ingot size and the rolled sheet thickness. The fatigue strength is varying following the ingot area and the orientation of cutting direction versus rolling direction.
