The current review goal to provide a thorough understanding of the nanocom- posite coating of steel for industrial applications. Based on findings from recent research, we will go into detail here about the several coating mate- rials, deposition methods, and the challenges associated with creating the best coating for steel. The two primary categories in which this article has been prepared are. In the first part, anti-corrosion coating, ceramic film, chemical vapour deposition, carbon nanotube, graphene has been presented with lat- est research. The second part focuses on industrial application of the current research including aerospace, automotive and petrochemical industry.
