摘要
The present invention provides a Zn-Al-Mg-Cr alloy-coated steel material with excellent corrosion resistance. A molten Zn-Al-Mg-Si-Cr alloy-coated steel material which is a steel material having a Zn-Al-Mg-Cr alloy coating layer and which has an interfacial alloy layer formed of coating layer components and Fe at the coating layer-steel material interface, wherein the interfacial alloy layer has a multilayer structure consisting of an Al-Fe-based alloy layer and an Al-Fe-Si-based alloy layer and furthermore, the Al-Fe-Si-based alloy layer contains Cr.
