Abstract: Low-cycle fatigue properties for three heats of normalized and tempered 2.25Cr–1Mo steel were investigated under uniaxial strain control at high temperatures. Comparing with the reference data for normalized and tempered, and annealed 2.25Cr–1Mo steels under uniaxial or diametrical strain control, it was clarified that the influence of heats, heat-treatments and the strain control mode.
