  • Iron and steel material having quenched surface layer part, method for producing the iron and steel material, and quenched component
    Patent number: 8545642
    Abstract: Providing an iron and steel material having quenched surface part, avoiding oxidation of a compound layer formed on the surface of the iron and steel material due to quenching, its production method, and an induction-quenched component. A quenched iron and steel material 10 comprises an iron and steel material 11, a compound layer 12 formed on the iron and steel material 11, and an antioxidant cover layer 13 formed on the compound layer 12. The iron and steel material 11 has a hardened layer having a given depth, and the surface of the iron and steel material 11 has enhanced hardness.
