Corrosion remains one of the most severe limitations to the use of low carbon steel in the manufacturing, construction, chemical, petrochemical industries. In this research work, the effect of tempering on the corrosion susceptibility of low carbon steel in seawater was evaluated. Low carbon steel purchased from a local market in Benin City, Nigeria was properly machined and divided into four samples. Sample A was the low carbon steel as received, sample B was water-tempered low carbon steel, sample C was oil-tempered low carbon steel, and sample D was brine-tempered low carbon steel. A tempering temperature of 700oC was used in this work. The samples were exposed to 1000 ml of seawater collected from sea in Warri, Delta State, Nigeria for a period of 100 days. The results obtained reveal that brine-tempered low carbon steel had better corrosion resistance and minimal weight loss when compared to other samples investigated. The study therefore recommends brine-tempered low carbon steel for equipment used in seawater.
