Abstract

PURPOSE:Providing the case hardening steel for cold plastic working - gas carburizing of which the coarsening behavior of the austenite crystal grains has been made substantially a gradual growth type at the gas carburizing treatment after the cold plastic working, by maintaining the content of the elements for regulating the crystal grain size so as to control the growth of the austenite crystal grains as low as possible.
