Abstract
The paper deals with the influence of cyclic loading (tension-compression, bending and torsion) on the course of the fatigue life and the fatigue limit of advanced low-alloyed strip steel with increased atmospheric corrosion resistance. The tested steel shows, besides very good mechanical properties (Re 380 MPa, A5 30%), also very good fatigue resistance and its fatigue limit/ultimate tensile strength ratio is above 0.5. These properties are provided by a favourable fine-grained structure of the tested steel.
Highlights
Low-carbon low-alloyed Cu-Cr-Ni-P steels serve as qualitatively higher substitution for classic structural materials able to form, under suitable atmospheric conditions, a coherent and very adhesive, aesthetic layer of corrosion products on its surface, which retards the corrosion process [1, 2]
The paper is focused on the assessment of the influence of the cyclic loading type on the fatigue life of sheets made of low-carbon low-alloyed steel with increased atmospheric corrosion resistance with higher utility properties
The external factors are related to the operational conditions of equipment
Summary
Low-carbon low-alloyed Cu-Cr-Ni-P steels serve as qualitatively higher substitution for classic structural materials able to form, under suitable atmospheric conditions, a coherent and very adhesive, aesthetic layer of corrosion products on its surface, which retards the corrosion process [1, 2]. The paper is focused on the assessment of the influence of the cyclic loading type on the fatigue life of sheets made of low-carbon low-alloyed steel with increased atmospheric corrosion resistance with higher utility properties. These sheets are used, among others, for products that are loaded in various ways during operation (e.g. ship transport containers). The environment has a significant influence, since corrosion accelerates the fatigue process even in case of steels with increased atmospheric corrosion resistance, to a less extent than in case of classic steels [4]
