Opis:: In this paper the authors introduce their own selected experimental results in the field of the investigation of fatigue resistance of structural steels. The experiments were carried out on the nine structural steels including high strength steels, DOMEX 700MC, HARDOX 400, HARDOX 450, 100Cr6 (UTS from 446 MPa to 2462 MPa) at high-frequency cyclic loading (f = 20 kHz, T = 20 ± 5 °C, R = -1) in the region of number cycles ranged from N ≈ 2×10⁶ to N ≈ 2×10⁶ cycles of loading. The continuous decrease of fatigue strength in dependence on the number of loading cycles was observed with the average value of ratio σ_a2x10⁹/ σ_a2x10 ⁶ = 0.69.

Opis:: This work presents a study of the fatigue properties in the example of Swedish steel Hardox 400. Fatigue tests were carried out in the area of high and ultra-high cycle region. From the practical point of view the durability of some components in the automotive industry and similar technical applications such as special semitrailers ranges between 10⁸ and 10¹⁰ cycles. But, only a few experimental results beyond 10⁷ cycles are available now. The main objective of this research was to provide independent results to the company which uses Hardox steel in the construction of semitrailers. Selected mechanical and fatigue tests were carried out with the aim to study fatigue properties of Hardox steel. Based on the obtained experimental results the fatigue properties of this still not well recognized type of steel are discussed.
