Abstract The hot compression experiment of AISI403 martensitic stainless steel was carried out by using Gleeble-1500D, and its flow stress was also investigated by means of microstructure analysis.The results show that the dynamic recrystallization of 403 steel occurs obviously at 950-1150℃ and strain rate from 0.01s-1 to 0.1s-1.The flow stress of 403 steel can be described well by a Zener-Hollomon parameter in the hyperbolic logarithm type equation.The regressed peak stress expression σP and the hot deformation activation energy Q of 403 steel during hot compression were concluded. Through the establishment of hot processing map, the best hot compression condition and the instability zones of flow behavior were acquired.
