Abstract

The corrosion behavior of carbon steels in Hunan province was comparatively studied via atmospheric exposure testing and atmospheric corrosion monitoring (ACM) technique, while the effects of environmental factors and the samples' shape on the corrosivity evaluation of atmospheric environments were assessed. The results showed that the corrosion rate of carbon steels have a positive correlation with SO₂ deposit rate in the atmosphere, while the Cl^- deposit rate becomes the important influence factor when the corrosion of carbon steels exposed in sites at or nearby a chlorine chemical plant. The corrosion rate of Q345 steel is higher than that of Q235 steel, and the corrosion rate of Q235 angle steel is higher than that of the Q235 flat steel. A linear relationship between the corrosion rate and the cumulative electric quantity measured by ACM was revealed for Q235 carbon steel, thus ACM technology can be used to predict the atmospheric corrosion behavior of carbon steels and assess the corrosivity of atmospheric environments.

Key words: Q235 steel Q345 steel atmospheric corrosion ACM technology
