Document Type and Number:
WIPO Patent Application WO/2019/026106
Kind Code:
A1
Abstract:
Provided is a zinc hot-dipped steel sheet having a zinc hot-dipped layer on at least one side of the parent material steel sheet, characterized in that: the Fe content of the zinc hot-dipped layer exceeds 0% but does not exceed 3.0%, and Al content exceeds 0% but does not exceed 1.0%; the zinc hot-dipped steel sheet has an Fe-Al alloy layer at the interface between the zinc hot-dipped layer and the parent material steel sheet; the thickness of the Fe-Al alloy layer is 0.1-2.0 µm; the difference between the maximum and minimum values for the thickness of the Fe-Al alloy layer in the width direction of the parent material steel sheet is within 0.5 µm; within the parent material steel sheet there is a refined layer which is in direct contact with the Fe-Al alloy layer; the average thickness of the refined layer is 0.1 µm to 5.0 µm, the average particle size of the ferrite phase within the refined layer is 0.1 µm to 3.0 µm; the refined layer contains or more types of oxides of Si and Mn; the maximum diameter of the oxides is 0.01 µm to 0.4 µm; and the difference between the maximum and minimum values for the thickness of the refined layer in the width direction of the parent material steel sheet is within 2.0 µm.
