Abstract: The study of the mechanical behavior of the austenitic Fe-18% Cr-8% Ni steel was carried out in the temperature range of 530°C - 680°C at a strain rate of 1×10-3 s-1, as well as at a temperature of 620°C and strain rates of 1×10-2 s-1 - 1×10-4 s-1. At these conditions, the PLC effect was observed. Type A serrations were observed in the temperature range 530 - 680°С. A decrease in the strain rate at a temperature of 620°C leads to a change in the type of serrations from type A to type B
