Abstract (English): This review examines the corrosive behavior of low-carbon steel in the presence of sodium hypochlorite (NaClO) and analogous environments, highlighting the importance of this material and the aggressiveness of the disinfectant. The central objective is to identify the most relevant corrosion mechanisms and the factors that influence their development. A comprehensive search of scientific databases was conducted, focusing on recent studies analyzing the corrosion of low-carbon steel in NaClO solutions, considering variables such as pH, temperature, and disinfectant concentration. The results reveal that sodium hypochlorite exhibits a high corrosive capacity compared to other chlorinated disinfectants, manifested through generalized and localized corrosion. Factors such as non-metallic inclusions on the steel surface and the hydrodynamic conditions of the medium play a significant role. Furthermore, the influence of the environmental surroundings, such as the presence of atmospheric pollutants, is a crucial aspect to consider. It was identified that ozonated water could be a less aggressive alternative in certain applications. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): La presente revisión examina el comportamiento corrosivo del acero de bajo carbono en presencia de hipoclorito de sodio (NaClO) y ambientes análogos, resaltando la importancia de este material y la agresividad del desinfectante. El objetivo central es i dentificar los mecanismos de corrosión más relevantes y los factores que influyen en su desarrollo. Se realizó una búsqueda exhaustiva en bases de datos científicas, enfocándose en estudios recientes que analizaran la corrosión del acero de bajo carbono en soluci ones de NaClO, considerando variables como el pH, la temperatura y la concentración del desinfectante. Los resultados revelan que el hipoclorito de sodio presenta una alta capacidad corrosiva en comparación con otros desinfectantes clorados, manifestándose a través de corrosión generalizada y localizada. Factores como las inclusiones no metálicas en la superficie del acero y las condiciones hidrodinámicas del medio desempeñan un papel significativo. Además, la influencia del entorno ambiental, como la presencia de contaminantes atmosféricos, es un aspecto crucial a considerar. Se identificó que el agua ozonizada podría ser una alternativa menos agresiva en ciertas aplicaciones. [ABSTRACT FROM AUTHOR]
