Abstract Scope In order to reduce the construction cost of hydrogen infrastructure facilities, application of inexpensive materials such as low alloy steel is required. For the application of materials of which hydrogen embrittlement is a concern such as low alloy steels, acquisition of material data in high pressure hydrogen gas and proof of safety are necessary, but the conduct of the test in high pressure hydrogen gas requires a large cost. In this study, as a simple evaluation technique of mechanical properties in high pressure hydrogen gas, concurrent cathodic hydrogen charging method which carried out mechanical test while introducing hydrogen electrochemically into steel was examined. When the tensile test at low strain rate was carried out in a continuous cathode hydrogen charging environment, fracture displacement equivalent to the test in high-pressure hydrogen gas was obtained.
