Abstract

The specific property of the weathering steel is its ability to create a protective patina layer on its surface in favourable environments. The weathering steel can be used without any corrosion protection and has considerably lower corrosion rate than standard carbon steel. The analytical corrosion prediction model for the calculation of corrosion losses is introduced in this paper. Methodology and results of experimental atmospheric corrosion tests are presented in this paper as well. The paper explains the high degree of correlation dependence between corrosion losses and thickness of corrosion products on a road bridge over a railway track in the city of Ostrava.
