Description	Based on the measurement of roll forces during the laboratory rolling of flat samples graded in thickness, new hot mean flow stress model of the HSLA steel of the type C-Mn-V-B was developed. It describes with a very good accuracy the mean flow stress m in the temperature range T = 850 – 1190 degree C, effective height reductions up to eh = 0.66, and strain rates in the range of ė = 8 – 103 s-1. The newly proposed model solves by phenomenological means a frequent problem with heteroscedasticity of relative deviations between the calculated and experimental values of deformation resistance in the case of the temperature effect. Mean flow stress values of steel C-Mn-V-B were compared with the formerly obtained m values for steels of type C-Mn as well as C-Mn-Nb-V. It was proved that HSLA steel with V and B displayed relatively very low deformation resistance and a minimum strain sensitivity at hot forming.
