Abstract:

The article presents the preliminary tests results of three high-strength steels, which are used in structural elements of semi-trailer’s construction. Paper presents an analysis of tensile and fatigue test results of high-strength steels like Hardox 400, Hardox 450 and Strenx 700MC. The fatigue tests are in the range from 104 to 107 number of cycles of applied load with a frequency of 40 Hz. The Wöhler curve shows the results of the fatigue properties of these steels, which are used in the construction of vehicles. Fatigue fractures were subjected to fractographic analysis in order to determine the mechanism of fatigue crack propagation. Fractographic analysis confirmed no effect of inclusions on the test results.

Keywords:

Fatigue crack, Wöhler curve, high-strength steels, high cycle fatigue tests, tensile test, semi-trailer’s components
