Abstract
This method for producing a steel member includes: a carburizing step of causing carbon to infiltrate into a steel member in an austenitized state by heating the steel member to a temperature equal to or higher than an austenitic transformation completion temperature, at a carbon concentration at which the steel member and the carbon have a hypoeutectoid composition, and removing cold from the steel member in which the carbon has been caused to infiltrate; and a quenching step of, after the carburizing step, heating the steel member again to a temperature equal to or higher than the austenitic transformation completion temperature, and rapidly cooling the steel member that has been heated.
