The operating temperature influence on the fatigue crack growth parameter, was analyzed by testing the
chromium-molybdenum steel for elevated temperatures application of the new generation additionally alloyed with
vanadium. The paper presents a comparison of the fatigue threshold value Kth and the fatigue crack growth rate
da/dN of the specimens cutting from pipe made of virgin steel, tested at room (RT) and operating (HT) temperature
of 540 C. The influence of the notch and crack initiation location, as well as the test temperature values, have a
decisive effect on the fatigue threshold values Kth of the investigated steel.
The macroscopic and microscopic specimens’ fracture surfaces are also shown. Obtained results of fatigue
crack growth parameter, correspond to the SEM micrographs of fractured surfaces.
