Corrosion Behavior of 0.06C Steel Sheets in Industrial Waters with Varying TDS Levels

This study examines the influence of water quality on the corrosion behavior of low carbon (0.06% C) steel sheets that are widely utilized in the construction of industrial sheds in local environments. The microstructural analysis of annealed steel samples was conducted using scanning electron microscopy, with grain size measured through the line-intercept method to assess structural characteristics. Corrosion testing was performed with Potentiostat using water samples sourced from four distinct locations, each with specific water quality parameters such as total dissolved solids (TDS), pH, and electrical conductivity. SEM–EDS analysis of the corroded steel surfaces revealed the formation of iron oxide layers, indicative of significant material degradation. The electrochemical test results demonstrated that water with higher TDS levels markedly accelerated the corrosion rate, emphasizing the profound impact that dissolved solids have on the deterioration of low-carbon steel. This research highlights the crucial role of water quality in influencing the long-term durability and structural integrity of steel infrastructures in industrial environments.
