Research Progress of Influence Law of Alloying Elements on Corrosion Resistance of Low Alloy Structural Steel

Abstract

Alloying control is an effective method to improve the corrosion resistance of low alloy structural steels. Different kinds of alloying elements have different influence law on the corrosion resistance of steels. In order to explore the effective method to improve the corrosion resistance of steel, the distribution law of alloying elements in steel as well as its influence mechanism and law on the corrosion resistance of steels were summarized in this paper. The research direction of regulation of the new generation of corrosion resistant steel in China was prospected. It was expected to provide a theoretical reference for the development of corrosion resistance regulation theory of low alloy structural steel and the research and development of a new generation of corrosion resistant low alloy steel in China.
