BLACK-PLATED STEEL SHEET |
| 摘要 |
A black-plated steel sheet has a Zn-plating layer containing molten Al and Mg, containing Al in the amount of 1.0-22.0 mass %, containing Mg in the amount of 1.3-10.0 mass %, and having a Zn black oxide distributed in a lamella pattern in the plating layer. The Zn black oxide is a Zn oxide derived from a Zn2Mg phase. The brightness of the surface of the Zn-plating layer containing the molten Al and Mg has an L* value of 60 or less. |
