Corrosion remains a critical challenge across various industrial sectors due to its substantial economic, environmental, and safety implications. Low carbon steel, despite its favorable mechanical properties and cost-effectiveness, is highly susceptible to corrosion, particularly in chloride-rich environments such as seawater. In recent years, the use of natural-based corrosion inhibitors has gained increasing attention as an environmentally friendly alternative to synthetic chemicals. This study investigates the effectiveness of guava (Psidium guajava) leaf extract, which contains active compounds such as tannins and polyphenols, as a corrosion inhibitor for low carbon steel in a seawater medium. The weight loss method was employed to determine corrosion rates, with inhibitor concentrations ranging from 7% to 11% over an immersion period of 288 hours. The results demonstrate that a concentration of 10% produced the most significant inhibitory effect, reducing the corrosion rate to 0.00011 mils per year and achieving a maximum inhibition efficiency of 73.17%. Other concentrations yielded efficiencies between 56.09% and 60.97%. These findings indicate that guava leaf extract has considerable potential as an effective and sustainable bioinhibitor capable of reducing corrosion in low carbon steel under harsh marine conditions. Overall, this study contributes to the development of green corrosion mitigation strategies and highlights the viability of natural plant extracts as promising alternatives to conventional synthetic inhibitors.
