The article presents the results of investigation into of the rheological properties of steel S355J2+N, while considering the influence of deformation, temperature and strain rate. Tests were carried out using a metallurgical process simulator Gleeble 3800. Based on the plastometric tests, stress–strain diagrams for the steel were developed and the coefficients of the flow stress function were selected. The obtained rheological testing results were used in computer simulations of the asymmetric plate rolling in the 3600 Plate Rolling Mill.
