High-temperature creep rupture behavior of modified 9Cr–1Mo steel used for steam cooler was investigated at temperature of 838 and 923 K and stress ranging from 100 to 250 MPa. Based on the analysis of creep rate–time curves, it is found that the creep rupture life decreases with the increase in the applied stress and temperature. The creep damage ...
