  • Patent number: 9598773
    Abstract: The present invention pertains to a method for producing a black-plated steel sheet capable of being blackened in a short amount of time, and exhibiting an excellent ability to maintain a black appearance after processing. As an original sheet, the sheet used is a Zn-plating steel sheet which contains molten Al and Mg and has a Zn-plating layer containing molten Al and Mg, containing Al in the amount of 1.0-22.0 mass %, inclusive, and containing Mg in the amount of 1.5-10.0 mass %, inclusive. The plating layer is blackened by causing the molten-plating steel sheet to contact water vapor inside a tightly sealed container. When doing so, the concentration of oxygen inside the tightly sealed container is 13% or less.
