The current paper discusses the selection of Manson–Haferd and Larson–Miller constants on correlation results of creep rupture property in several heat-resistant steels. It indicates that the change in Larson–Miller constant has obvious effect on the predicting result of rupture life and the optimal values will depend on materials and the optimal ranges of the values are narrow. However, for Manson–Haferd constants and , they are at least phenomenally not independent variables but show a linear relationship: . It is shown that the values of Manson–Haferd constants can be selected in a wide range with desirable correlation accuracy and a set of Manson–Haferd constant is recommended to correlate the creep rupture data.
