Evaluation of the corrosion resistance of steel elements in the industrially aggressive environments using the accelerated corrosion testing methods

Abstract

This work presents the methods for testing the resistance of materials due to corrosion of structural steel, in the presence of corrosion agents in the immediate vicinity of the industrial complex RTB in Bor. General corrosion testing was performed near the Sulfuric Acid Plant, Electrolytic Refining Plant and next to the automatic air quality monitoring station in Bor for 6 months, as well as in the salt chamber for 120h and 240h and by immersion of samples in electrolyte solution from the Electrolytic Refining Plant for of a month. The results were compared with the standard samples stored in the laboratory. A method based on measuring the loss of mass was used to evaluate the material corrosion resistance. Samples are rectangular, dimensions adopted according to the standard EN 10002-1. The steel used is S235, and its mechanical characteristics were obtained from the tensile test.
