| Abstract: | Creep life prediction is an important issue for components used for nuclear breeders at high temperature. Through analysis on creep data of 316 H stainless steel served in reactor vessels, the steady state creep rate equation was obtained by rate temperature parameter model. Reasonable statistical test results supported the reliability function of creep property. σ-RTP-R curves and T-σ]-R curves were proposed for 316 H stainless steel based on the distribution of Z′-parameter in this research. The allowable stresses in service temperatures from 550 °C to 700 °C are also obtained according to the standard methods specified in ASME BPVC. The results demonstrate that RMB’ model has not only good precision in comparison of other existent creep models, but also high prediction accuracy. The experimental creep data completely drop into the 99.7% confidence interval of predicted results by reliability function. The steady state creep behavior and allowable stress of 316 H stainless steel in experimental conditions can be well evaluated by the present model. |
