PLATED STEEL SHEETS AND PARTS INCLUDING SUCH PLATED STEEL SHEETS

Abstract

The present invention provides a galvanized steel sheet including a base steel sheet and a galvanized layer arranged on the surface of the base steel sheet, wherein the base steel sheet has a chemical composition including, based on mass %, Ni: 0.010 to 1.000%, Cu: 0.010 to 1.000%, and Sn: 0.003 to 1.000%, and in an elemental distribution image obtained by measuring a cross-section of the galvanized steel sheet with EPMA, the surface coverage of the area covered with a surface concentration of at least one of Ni, Cu, and Sn satisfying [Ni]+[Cu]+0.6[Sn]≥10 and with a surface concentration of Fe of 10 mass % or more is 25% or more, and the average length of the uncovered area not covered by at least one of Ni, Cu, and Sn is 10 µm or less, and the portion covering the galvanized steel sheet.
