Document Type and Number:
WIPO Patent Application WO/2022/191213
Kind Code:
A1
Abstract:
The present invention provides a hot dipped Al-Zn-Si-Mg coated steel sheet which stably has excellent corrosion resistance. In order to achieve the above-described purpose, the present invention provides a hot dipped Al-Zn-Si-Mg coated steel sheet which has a coating film and is characterized in that: the coating film has a composition that contains 45 to 65% by mass of Al, 1.0 to 4.0% by mass of Si and 1.0 to 10.0% by mass of Mg, with the balance being made up of Zn and unavoidable impurities; and the Ni content in the unavoidable impurities is 0.010% by mass or less relative to the total mass of the coating film.
