摘要：	Gaseous hydrogen is one of several potential fuel sources that can replace fossil fuels in several different sectors of the US economy, especially the transportation (automobiles) and home heating. Supply of these sectors would require large volumes of gaseous hydrogen to be moved economically to major metropolitan. Currently the most economical method for transmission of the volume of hydrogen gas required is under pressure through transmission steel pipelines. As transmission pressures are increased, steel pipelines that could be used for the transport of hydrogen at pressure can be prone to hydrogen embrittlement at the welds, the heat-affected-zone and/or the base metal regions of the pipeline. Over the past few years, significant advances have been made in understanding the mechanisms of hydrogen embrittlement in a wide variety of materials and in materials technologies. However, specific data related to traditional pipeline steels in the presence of gaseous hydrogen under pressure is lacking.
