Abstract: The effect of volume fraction of ferrite and bainite phases in the structure of low-alloy carbon steels on static and fatigue properties was studied. It is shown that the proportion of ferrite <0.2 in the metal structure changes the deformation mechanism from shear to rotational, depending on the phase composition
