Title:
HOT-DIP PLATED STEEL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/157974
Kind Code:
A1
Abstract:
The present invention is a hot-dip plated steel material having a plating layer on the surface of a steel material, the plating layer comprising over 22.5% and up to 50.0% of Al, over 3.0% and up to 15.0% of Mg, 0.03-0.6% of Ca, 0.03-1.0% of Si, and 2-25% of Fe, with the remainder made up by Zn and impurities. In an X-ray diffraction pattern of the plating layer surface, measured under conditions in which a Cu-Kα ray is used and the X-ray output is 50kV and 300 mA, I1 obtained from the X-ray diffraction peak of Al0.5Fe1.5 is 1.1 or above, and I2 obtained from the X-ray diffraction peaks of Zn, Al, and MgZn2 is 0.25 or below.
