METHOD FOR PRODUCING HOT-DIP GALVANIZED STEEL MATERIAL, AND HOT-DIP GALVANIZED STEEL MATERIAL

摘要

The purpose of the present invention is to provide: a method for producing a hot-dip galvanized steel material in which wettability with respect to molten zinc is good and plating defects are not generated; and a hot-dip galvanized steel material. In the method for producing a hot-dip galvanized steel material, a flux treatment and a drying treatment are performed on the surface of a steel material to be plated and a hot-dip galvanizing bath immersion treatment is subsequently performed in which the steel material to be plated is immersed in a plating bath having a component composition that includes 97.5 mass% or more of Zn, 1.5 mass% or less of Fe, 0.10 mass% or less of Pb, 0.01 mass% or less of Cd, and 0.001-0.05 mass% of Mg.
