Prediction capability of a newly derived hot flow stress model is demonstrated on experimental flow curves of steel 38MnVS6. These flow curves were also described by the commonly used equations like Cingara & McQueen, JMAK or Hensel-Spittel. Graphical and statistical comparison proved that flow curve prediction by the newly derived model leads to the best fit with the experimental data. An advantage of the new model was discovered especially in case of the flow curves acquired in very broad range of thermomechanical conditions when shapes of these curves may very differ.Keywords: hot compression flow curves, flow curve characteristic points, hot flow stress model
