The effect of the strain accumulation by changing the number of rolling passes on the rolling force, structure and mechanical properties of austenitic Cr-Ni-Ti stainless steel with different carbon contents has been studied. An increase of the number of passes for a given overall reduction was found to have a beneficial effect on tensile properties while maintaining adequate ductility. At a rolling temperature of 1100 - 1150 °C with rolling in 1-3 passes, an increase in carbon content leads to acceleration of softening processes. With a lower rolling temperature and an increased number of passes, the reverse effect is obtained. When working out rolling schedules for sequences in HTMP conditions involving cooling before the final passes, residual hardening must be taken into account in rolling force calculations to prevent to prevent the mechanical equipment of the rolling stand from the breakage.
