Engine components, such as injection systems, are subjected to a large number of load cycles (N > 1E7) during their lifetime and are exposed to potentially corrosive media such as fossil fuels. For this reason, corrosion fatigue in the very high cycle fatigue (VHCF) regime has to be taken into account for a reliable fatigue design. Biofuels are potentially more corrosive than unblended fuels due to the hygroscopic properties. This is caused by additives, for example ethanol. In this contribution, the impact of corrosion fatigue has been investigated on notched and unnotched specimens of chromium stainless steel 1.4016 (X6Cr17), in air and E85 biofuel (gasoline fuel with 85% ethanol added). The results have been obtained under tensile cyclic loading conditions (R = 0) using different test rigs to investigate the influence of frequencies.
