    摘要： 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. A method for producing the iron and steel material 10 comprises a first step for forming the antioxidant cover layer 13 to cover the compound layer 12 formed on the iron and steel material 11, and a second step for applying induction hardening to the iron and steel material 11 having the compound layer 12 and the antioxidant cover layer 13, with the temperature increased in a given heating time until the given heating temperature is reached, and with cooling immediately performed once the heating temperature is reached.
