Abstract Hot��cold fatigue performances of the same kind of steel at different temperatures in different ways were studied. One way is via controlling the test temperature strictly, and another is through test standard. The results showed that all the cracks were initiated from the notch. The fatigue crack based on the experimental is larger. When the controlled temperature is closer to the room temperature, the two sets of test data are closer as well.
