The regulations of true stress–true strain cures were analyzed at different working conditions. Based on the experimental data, the hyperbolic sine, the exponential and the power constitutive models were established describing the high temperature flow peak stress of the steel. The peak stresses were predicted by the constitutive equations under the corresponding experimental conditions. The accuracy and reliability of the equations were evaluated. The results show that when the peak stress is predicted by the hyperbolic sine model, the consistency between the experimental and calculation values is the best. The correlation coefficient (R) is 0.998, and the average value of relatively errors is 4.9%. These will provide a basis of theory for selecting plastic deformation constitutive model of the steel at high temperature.
