After twenty two years of operation,the high temperature shift reactor has generated serious failure caused by hydrogen corrosion This paper analyses the reason of the hydrogen corrosion of the high temperature shift reactor Measures such as hydrogen diffusing and adding inner insulating layer were taken which have extended the service life of this equipment effectivel

Susceptibility to hydrogen embrittlement and dehydrogenation annealing process of bainite steel used for crossing;

Improvement of Dehydrogenation Annealing Technology for Forgings of Steel 45Cr2NiMoVSi;

Based on the state of hydrogen in steel and the relation between the solubility and the diffusion coefficient of hydrogen , dehydrogenation annealing technology for forgings of steel 20CrNi2MoA has been scientifically designed.
