Document Type and Number:
Japanese Patent JP7097492
Kind Code:
B2
Abstract:
To provide a coated steel sheet having stably superior corrosion resistance and processed-part corrosion resistance.SOLUTION: The present invention pertains to a coated steel sheet comprising a coating film formed on a plating coating directly or via a chemical conversion coating. The plating coating contains Al: 45-65 mass%, Si: 1.0-4.0 mass% and Mg: 1.0-10.0 mass%, with the balance being Zn and inevitable impurities. The diffraction intensity of Si and Mg2Si in the plating coating by X-ray diffraction satisfies the relationship (1): Si (111)/Mg2Si (111)≤0.8 (1).SELECTED DRAWING: None
