With the rapid development of hydrogen related equipment, how to ensure the reliable operation of these equipment has been an important research topic. 2.25Cr1Mo0.25V steel has high strength, good resistance to hydrogen corrosion and low cost. So it becomes one of most used material for high temperature and high pressure hydrogen systems. In this paper, the glycerine gas gathering experiment, micro hardness test and dynamic tensile experiment were conducted to study the changes of the mechanical properties of 2.25Cr1Mo0.25V steel under varying hydrogen charging time. The relationship between the hydrogen content and material properties were also discussed in detail.
