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.

Based on analysis of the characteristic,shape of squeeze roller and the prevention and cure of "grain inheritance" and dehydrogenation of the heavy squeeze roller made of 42CrMo steel,the heat treatment process including one time of pretreatments,two times of preheating,two times of normalizations,three times of bainite isothermal treatment and one time of dehydrogenation,was proposed.
