Abstract In order to provide dates for realizing the structure and property prediction system of 403Nb blade steel hot tandem rolling, the hot compression was carried out using the Gleeble-3500. According to the experimental dates, the parameter Z and flow stress equation were worked out respectively: ，σP＝14.5926ln ＋1002406.111•T－1－604.613658. The analysis of the structure shows that the 403Nb dynamic recrystallization forms the nuclear under the bulging mechanism. There are a few thin twins with width 30~100nm. The NbC particles in the matrix can stick the dislocations, which improves the hot deformation activation energy.
