Abstract:
This method for producing a steel member includes: a carburizing step in which an austenitized steel member obtained by heating a steel member to at least an austenization completion temperature is subjected to carbon infiltration at a carbon concentration at which the steel member and carbon form a hypoeuctectic composition, and the carbon-infiltrated steel member is subjected to annealing; and a quenching step in which, after the carburizing step, the steel member is reheated to at least the austenization completion temperature and the heated steel member is rapidly cooled.
