HOT-DIP Zn-Al-Mn ALLOY PLATED STEEL HAVING EXCELLENT CORROSION RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide hot-dip Zn-Al-Mn alloy plated steel having excellent corrosion resistance.;SOLUTION: The hot-dip Zn-Al-Mn alloy plated steel having excellent corrosion resistance has a plated layer having a composition consisting of, by mass, 35-85% Al, 0.5-10% Mn, and Si in an amount of 0.5-10% of Al content, and the balance Zn with inevitable impurities. The plated layer preferably further contains 0.1-5% Mg and 0.05-5% Cr.;COPYRIGHT: (C)2004,JPO&NCIPI
