Abstract

This research aims to investigate the effect of bending angle and immersion in acidic corrosive media on the corrosion rate of low carbon steel ST37. ST37 is commonly used in engineering applications due to its good formability, but it has low corrosion resistance, especially when subjected to mechanical deformation such as bending. The experimental method involved three variations of bending angles: 70°, 90°, and 95°, and three types of corrosive solutions: NaCl, HCl, and H₂SO₄ (98%). Each specimen was immersed in the corrosive media for 2 hours, and the corrosion rate was calculated using the gravimetric method based on the weight loss before and after immersion. The results showed that increasing the bending angle significantly increased the corrosion rate. Additionally, the type of corrosive media played a major role, with HCl producing the highest corrosion rate, followed by H₂SO₄, and the lowest was NaCl. The combination of a 95° bending angle and HCl solution resulted in the highest corrosion rate, with an average exceeding 2800 mpy. This indicates that plastic deformation due to bending and exposure to highly aggressive corrosive environments synergistically accelerate the degradation of ST37 steel. The study concludes that both bending angle and corrosive media type directly affect the corrosion resistance of ST37 steel. Therefore, additional protective measures and environmental control are essential when applying this material in structures subjected to mechanical deformation.
