Description
Summary:Hydrogen embrittlement property of high strength steels has widely been evaluated for wire and bolt products. But there are not many evaluation methods of hydrogen embrittlement for steel sheets. In this work, a method for sheet products has been established. Using this method, effects of materials (tensile strength), applied stress and pre-strain on hydrogen embrittlement property can reasonably be evaluated for high strength steel sheets. Environmental embrittlement evaluation in cyclic corrosion test was also carried out for comparison with the results from the new method, which were in good agreement.
