Abstract The dynamic charging does not influence on the creep rate of type 321 austenitic stainless steel if the initial strain was less than 2%, in which the amounts evolving hydrogen after test were below 1.5 ppm (by wt). However, the creep rate increased markedly when the initial strain was larger then 8% or the specimen was precharged for a long time. In the case the corresponding amount evolving hydrogen was 5 to 12 ppm (by wt).
