The degradation effect of hydrogen on the mechanical properties of steels is well known, but still not sufficiently understood. The fast and safe market ramp up of hydrogen technologies makes it evident to evaluate a wider understanding of this topic. In general it is often described as hydrogen embrittlement. Therefore it is desirable to achieve a test method which is able to provide material properties under hydrogen atmosphere in an easy way. Currently mechanical tests under hydrogen atmosphere are executed in autoclaves. For this technique complex hardware is needed, therefore tests are expensive and test capacities are only available in a small scale. The shown test method promises a trendsetting approach for reducing costs and machine time by using hollow specimen.
