Corrosion resistance of corten steel-A review

Corrosion which encompass material science, chemistry, physics, metallurgy and chemical engineering is a topic of interest to interdisciplinary research groups. In order to comprehend the process of corrosion, it is important to understand the reaction which takes place between the corrosive layer and the steel surfaces. Corten steel which is a type of weathering steel is a low alloy steel, well known for its property of corrosion resistance. These steels are widely used in the construction of bridges, towers and in several applications of architecture also. The present work provides a short analysis done by several investigators on the corrosion of corten steel. This review discusses the problems such as corrosion rates and the formation of rust layer at different exposed conditions. Finally, the effects of alloys and the long-term behavior of the corten steel has also been reported. (c) 2020 Elsevier Ltd. All rights reserved.
