HOT-PRESS-MOLDED ARTICLE AND PRODUCTION METHOD FOR SAME, AND PLATED STEEL SHEET FOR USE IN HOT-PRESS MOLDING

摘要

Provided are a hot-press-molded article that has excellent resistance spot weldability, and that does not require a process such as shotblasting to remove oxides; a production method for the same; and a plated steel sheet for use in hot-press molding. The plated hot-press-molded article is obtained by heating a plated steel sheet to a temperature at or above the Ac3 transformation point of the plated steel sheet, and then simultaneously cooling while molding the sheet with a mold. An oxide layer having a network of asperities, having average roughness Ra of at least 2 μm and average thickness of no more than 3 μm, is present on the plated surface, and below the oxide layer is a plated layer having a melting point that is no higher than the aforementioned heating temperature.
