Abstrak

Corrosion is usually called rusting. Corrosion in low carbon steel is carried out by the circulation method and without circulation. The specimens were placed in 0.5% HCl solution of 3 specimens in 1 vessel. The test specimens totaled 27 specimens in 3 vessels. In this study, low carbon steel immersion was carried out with circulation of 1200 L / H and 800 L / H and also without circulation with immersion times of 5, 10 and 15 days. The highest corrosion rate was obtained in low carbon steel soaked in 0.5% HCl for 15 days with a circulation of 1200 L / H which is 0.07357 mpy. The lowest corrosion rate was obtained in low carbon steel soaked in 0.5% HCl for 5 days without circulation, which is 0.02681 mpy.
