HOT-DIPPED GALVANIZED STEEL MATERIAL HAVING EXCELLENT WELDABILITY AND PRESS WORKABILITY AND MANUFACTURING METHOD THEREFOR
摘要:
Disclosed are a hot-dipped galvanized steel material and a method for manufacturing the same. The hot-dipped galvanized steel material comprises an iron substrate and a hot-dipped galvanizing layer formed on the iron substrate, wherein the hot-dipped galvanizing layer comprises, by wt%, 0.01 to 0.5% of Al, 0.01 to 1.5% of Mg, 0.05 to 1.5% of Mn, 0.1 to 6% of Fe, and the balance of Zn and inevitable impurities, with a Zn-Fe-Mn based alloy phase present at the interface between the iron substrate and the hot-dipped galvanizing layer, and an area ratio of the Zn-Fe-Mn-based alloy phase to the hot-dipped galvanizing layer ranging from 1 to 60%.
