Quantitative investigations of hydrogen dependent properties of aircraft landing gear materials have only scarcely been carried out in the past. They are essential for respective component life time assessments. To better understand the behavior of these landing gear materials in a hydrogen rich environment, specimens were charged in the condition as delivered with known concentrations of hydrogen and then mechanically tested to evaluate the degradation effects. The present contribution is focused on evaluating the hydrogen concentration dependent material properties and the respective fracture topographies of the two investigated steels, and then continued by the comparison of the results with other previously investigated martensitic steels in order to better understand the thresholds for these materials to maintain structural integrity.
