METHOD FOR PRODUCING BLACK PLATED STEEL SHEET AND METHOD FOR PRODUCING MOLDED ARTICLE OF BLACK PLATED STEEL SHEET |
摘要 |
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 0.1 22.0 mass% inclusive and containing Mg in the amount of 0.1 1.5 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. |
