FLUX COMPOSITION FOR HOT DIP Zn-Al BASED ALLOY PLATING AND METHOD FOR PRODUCING HOT DIP Zn-Al BASED ALLOY PLATED STEEL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flux composition with which uniform hot dip Zn-Al based alloy plating having a fine appearance can be easily attained, and to provide a method for producing hot dip Zn-Al based alloy plated steel using the same.;SOLUTION: In the flux composition for hot dip Zn-Al based alloy plating composed of an aqueous solution comprising Cl and Cu, Cl and Cu satisfy, by mass%, Cl/Cu=1.2 to 10 and 1%≤Cl+Cu≤50%. The method for producing hot dip Zn-Al based alloy plated steel uses the same.;COPYRIGHT: (C)2005,JPO&NCIPI
