    strength was also higher than that of 10CrMo9-10 steels. Long-term service of steel at elevated temperature in creep conditions leads to its degradation through a number of changes running in the microstructure, contributing to a decrease in functional properties. In consequence, it can lead to damages in elements or constructions [1, 2].Some results are removed in response to a notice of local law requirement. For more information, please see here.
