The Construction Industry Employs Corrosion Protection Mechanisms

Abstract

Corrosion-resistant steels are becoming more prevalent in contemporary manufacturing due to their expanding range of applications. They are increasingly utilized in the construction, marine, and shipbuilding industries. They are a crucial category of long-lasting structural materials. Simultaneously, these construction materials might become highly susceptible to localized corrosion damage in specific situations. The theoretical section illustrates stainless steel categorization. The text describes the corrosion resistance of stainless steels and the various elements that influence it. The text provides a comprehensive description of all corrosion mechanisms, with a particular focus on the genesis of pitting corrosion and the impact of external influences on this specific corrosion mechanism. The study focuses on the impact of changing the chloride concentration in aqueous acids on pitting corrosion development. The experimental phase of the study involved conducting electrochemical corrosion tests to investigate the effect of chloride on stainless steel corrosion resistance. The experiments used austenitic stainless steels (AISI 321, AISI 316L, and UNS S31050), as well as duplex steel (AISl 2304) and superduplex stainless steel (AlS 2507). We tested these materials in water containing varying levels of chloride (50 ppm Cl, 1900 ppm Cl, and 19000 ppm Cl). We then measured and analyzed the electrochemical corrosion parameters. Following the experimental phase, the data was examined, and a conclusion was reached based on the findings. Kijune mentioned the topics of building construction, stainless steel, corrosion, and chlorides. DOI: https://doi.org/10.52783/tjjpt.v45.i02.6371
