PROBLEM TO BE SOLVED: To provide a flux for a hot dip galvanizing, a flux bath for hot dip galvanizing, and a method for manufacturing a hot dip galvanized steel which provide excellent wettability to molten zinc, so as not to cause non-plating even when a Pb density contained in a hot dip galvanizing bath is extremely low.SOLUTION: A flux for a hot dip galvanizing includes zinc chloride of 30-80 mass%, ammonium chloride of 15-60 mass%, and third chloride of 4-34 mass%. The third chloride includes at least manganese chloride. |
