| Abstract: | Study has been made of on fatigue crack propagation Cr-Mo steels under hydrogen attack. The emphasis is put on the feature of fatigue crack propagation of the steel under different temperature, attack time, pressure and load ratio. The tendency has been found that affect the efficiency of Paris formuls. Hence, the both theoretical &experimental has been provided for life predication,safe appreciation and reliabile design of petrochemical pressure vessels. |
