Abstract: The hydrogen embrittlement sensitivity of L245 pipeline steel was compared and studied by electrochemical hydrogen charging tensile test at different tensile rate of 2 mm/min and 0.02 mm/min. Metallurgical microscopy and scanning electron microscopy（SEM） were used to characterize and analyze the microstructure and fracture morphology of L245 pipeline steel. The results show that with the extension of hydrogen charging time, the variation trend of the strength of the hydrogen charging tensile specimens is similar under the two tensile rates, and similar morphology is observed on the fracture surface,and the difference of hydrogen sensitivity index is small. With the extension of hydrogen charging time, the hydrogen sensitivity of L245 pipeline steel increases at the tensile rate of 2 mm/min. Under the experimental hydrogen charging current density of 15 m A/cm² and hydrogen charging time of 24 h, it is feasible to evaluate the hydrogen embrittleness sensitivity of L245 steel with the tensile rate of 2 mm/min.
