Patent ID: 10844456

Abstract:
Provided are: a cold work tool having excellent wear resistance; and a method for manufacturing the cold work tool. A cold work tool which has an ingredient composition that can be prepared into a martensite structure by quenching and which has a martensite structure, wherein the hardness of the cold work tool is 58 HRC or more, the area ratio of a carbide having an equivalent circle diameter of 5 μm or more in the cross-sectional structure of the cold work tool is 4.0% by area or more, and the carbon solid solution fraction, which is expressed by the ratio of the mass ratio of the amount of carbon that is present in the form of a solid solution in the structure of the cold work tool to the mass ratio of the amount of carbon that is contained in the whole of the cold work tool, is 75.0% or more. A method for manufacturing a cold work tool, which is suitable for manufacturing the aforementioned cold work tool.
