Zinc hot dip galvanized steel plate excellent in press formability and method for production thereof

摘要

A hot-dip galvanized steel sheet includes a plating layer substantially composed of the eta phase and an oxide layer disposed on a surface of the plating layer. The oxide layer has an average thickness of 10 nm or more and includes a Zn-based oxide layer and an Al-based oxide layer. A method for producing the hot-dip galvanized steel sheet includes a hot-dip galvanization step, a temper rolling step, and an oxidation step.
