Abstract
The present invention relates to a plated steel sheet having a high LME resistance. The plated steel sheet of the present invention has a tensile strength of 780 MPa or more and a predetermined chemical composition. The plating layer contains Zn. A depth in a thickness direction of the steel sheet from an interface of the steel sheet and the plating layer wherein a C concentration measured by GDS is 0.05% or less is 8 µm or more, a thickness in a thickness direction of the steel sheet from an interface of the steel sheet and the plating layer of the layer with an area ratio of the ferrite phase of 90% or more is 8 µm or more, and at a position of 4 µm in a thickness direction of the steel sheet from an interface of the steel sheet and the plating layer, the solute amounts of the metal Si and metal Al in the ferrite phase are a total of 0.3% or more.
