The paper is concerned with the mathematical model for the computation of the technological as well as force and energy parameters during rolling of austenitic steel sheets and strips at elevated temperatures. On the basis of the computation results obtained for 18–8 type chromium‐nickel steel (marked 1H18N9T) universal nomograms have been designed for a wide range of strip width and roll diameters. They allow the evaluation of force parameters, energy consumption and average temperature in the roll pass depending on the reduction and strip initial temperature as well as strip relative thickness. The presented nomograms might be helpful in designing the technology for warm rolling of austenitic steel sheets and strips as well as conventional cold‐rolling, taking into consideration thermal effects in the deformation zone.
