Fatigue Properties of Selected Steel

In the contribution the fatigue properties at cyclic stress in tension and bending are presented. The properties were analysed for low alloyed and microalloyed steel 1 to 4 mm in thickness different surface finish/natural, pickled, zinc coating/. The properties were studied also on steel grades with increased resistance to corrosion, with different Cu contents. The results suggested correlations of surface finish and fatigue resistance. Experiments and the analyses confirmed that the fatigue properties of these new developed steel are at least not worse than that for the usual grades of the same class.
