Corrosion effect of 20 % NaCl solution on basic carbon structural S235JR steel

Abstract

All structural steels offer economical properties of mean strength and low corrosion resistance. There are ferritic-perlitic steels and very often used as construction materials in industrial applications. The purpose of this article is to investigate corrosion resistance using weight loss and profile roughness parameters of typical structural steel in grade S235JR in 20 % NaCl solution in distilled water. Corrosion tests show that the tested steel in both corrosive environments is characterized through continuous corrosion. Roughness parameters for every of the research times determine the size of steel corrosion.
