Outline
As a kind of revolutionary steel material, Zn-Al-Mg coated steel is gradually becoming the ideal substitute of traditional galvanized steel sheet and Al-Zn alloy coated steel sheet due to its excellent corrosion resistance and edge trimming protection effect as well as good formability and surface appearance. In this paper, it is reviewed the chemical composition system, effects of various elements, current status of research and development at home and abroad as well as patents and researches on application technologies for Zn-Al-Mg coated steel. Moreover, it is mainly sorted out and compared the composition design, microstructure characteristics and performance features of Zn-Al-Mg coated products of different systems in Japan, Europe and China. Finally, the future development trend of Zn-Al-Mg coated steel is expected to provide references for further research and development and applications of this material.
