Zusammenfassung:	The present disclosure relates to a steel and a method for manufacturing the steel. Specifically, the present disclosure is characterized by providing a method for providing optimal alloy components that can reduce carburizing thermal deformation by reducing contents of Cr and Mo elements compared to the existing ones, and improving the physical property with fatigue resistance of a carburized steel by adjusting a rolling thermal treatment temperature, a carburizing thermal treatment condition, and the like to increase a fraction of a fine MX precipitate and improve a precipitation strengthening effect.
