The effect of austenization temperature on the microstructure and on the time to failure due to creep of steel 10Kh9V2MFBR is studied. The microstructure and the mechanical properties of the metal are determined after tempering at 730°C preceded by normalizing from 1050 and 1150°C. It is shown that in order to attain the highest creep resistance the austenization temperature of steel 10Kh9V2MFBR should not exceed 1050°C.
