The properties of railroad rails produced from bainitic steels are compared to those from traditional pearlitic steels. Formation and propagation of contact fatigue cracks in the rails is considered. It is shown that bainitic steels exhibit a better combination of strength and ductility characteristics than pearlitic steels.
