Abstract

A hot-dip plated steel material has a plating layer on a surface of a steel material, in which the plating layer contains Al: more than 22.5% and 50.0% or less, Mg: more than 3.0% and 15.0% or less, Ca: 0.03 to 0.6%, Si: 0.03 to 1.0%, Fe: 2 to 25%, and a remainder consisting of Zn and impurities, and, in an X-ray diffraction pattern of a surface of the plating layer, measured under conditions in which an X-ray output is a voltage of 50 kV and a current of 300 mA using a Cu-Kα ray, Iobtained from an X-ray diffraction peak of AlFeis 1.1 or more, and Iobtained from X-ray diffraction peaks of Zn, Al, and MgZnis 0.25 or less.
