The hot pressure deformation tests were carried out by using Gleeble-2000 simulator at the temperature of 950 ℃ ~ 1150 ℃ and strain rate of 0.001s -1 ~ 1s -1 for a kind of high strength construction steel 34CrNiMo6 for Crankshafts and the curve of its flow stress were obtained. By studied the data, the flow stress constitutive equation, hot deforming active energy and the Z parameter were obtained. The curve of flow stress of 34CrNiMo6 steel indicated that the flow stress was increased with the

It was propitious to dynamic recrystallization with raising temperature or reducing strain rate, and also made for the refinement of grain.
