Zusammenfassung:A steel raw material applied to manufacture of a cold working die with a hardness of 58HRC or more, is cut for use as a prehardened steel material having a size corresponding to a dimension of the cold working die. The steel raw material is a steel raw material for a die having a quenched and tempered structure and hardness of 58 HRC or more. The steel raw material for a die contains 2% by area or less of primary carbides having a circle-equivalent diameter of 5 µm or more in a cross-sectional structure of the steel raw material. Furthermore, manufacturing method of a steel raw material for a die that is preferable to obtain the steel raw material for a die, a subsequent manufacturing method of a prehardened steel material, and a manufacturing method of a cold working die are provided.
