Behavior of hardening parameters for viscoplastic constitutive equations was discussed on the basis of the experimental results of type 316 stainless steel for a wide range of temperatures from room temperature to 7000℃. It was elucidated first that the cyclic hardening under proportional loading can be described by the expansion of the range of kinematic hardening variables at each temperature. This behavior is especially significant around 500℃. For cyclic hardening under non proportional loading, on the other hand, marked development of isotropic hardening was observed. Then, new evolution equations of kinematic hardening were proposed by incorporating these results. The applicability of the resulting constitutive models was demonstrated by comparing the predictions with the corresponding result of the experiments.
