Summary:The influence of the corrosive environment on strength characteristics of heat-resistant alloys at high temperatures is discussed. The results of corrosion tests for two heat-resistant nickelbased alloys simulating the processes of alloy sulfide-oxide corrosion during operation are presented. Extrapolated values of specific mass changes for 5000 h at temperatures of 600–750 °C were determined using the mathematical models obtained for tests lasted up to 1000 h.
