Storage tanks and pipelines of gaseous fuel are frequently installed in low temperature environment. So, when gaseous fuel contains hydrogen, not only cryogenic embrittlement but also hydrogen embrittlement may occur in the equipments. In this report, the effect of hydrogen on brittle-ductile transition of COR-TEN O steel was studied by carrying out fracture experiments of hydrogen charged and non-charged materials over the temperature range from -196°C to room temperature. The variations of fracture resistance expressed by CED with temperature for hydrogen charged and non-charged materials are compared. As the result, it is shown that the brittle-ductile transition temperature of hydrogen charged material is lower than that of non-charged one and, although the fracture resistance of charged material naturally becomes smaller in the upper shelf range, not the fracture resistance of non-charged material but that of charged one is a little bit larger in the brittle-ductile transition range.
