Description
Summary:The state-of-the-art report consist of an overview and a summary of the mechanical behaviour of pipeline steels (in the range of X42-X70) when exposed to electrochemical charging and gaseous hydrogen environment. Experimental data from tensile-, fracture -and fatigue tests in air and hydrogen environment are addressed and presented in correlation with the identifications of the possible key mechanisms behind hydrogen embrittlement degradation. In addition, the effect of parameters such as metallurgy, temperature, pressure, gas composition and load conditions are included.
