Corrosion Behaviors of U75V, U76CrRE Heavy Rail Steel in Simulated Industrial Atmosphere

Abstract:

The corrosion of heavy rail steel is severity in south. Now there are not studies on the corrosion of heavy rail steel in atmosphere. The corrosion of heavy rail steel were studied by periodic infiltration corrosion test and electro-chemical testing technique in simulated industrial atmosphere. The result showed that U76CrRE has apparently more excellent anti-corrosion ability than that of steel U75V. The Cr and Re in U76CrRE enriched in local of base that promotes the rapid generation of α FeOOH and the increase of content. Thus the ability of the rust layer against the corrosive media from entering the layer was improved. Anti-corrosion capacity of heavy railroad steel in industrial atmosphere can be improved significantly by adding Cr and RE alloy.
