The probabilistic life prediction of high temperature components was studied by using the stochastic equation of creep damage and simple second-order theory and method of high temperature components. The relation between the life and the reliability of high temperature components was derived by using the probabilistic calculation of high temperature components and considering the working condition of high temperature components. The calculation accuracy was largely increased by fully considering the random and relative of parameters.
