This study aims to determine the effect of holding time and oil viscosity on the S45C steel hardening process on the corrosion rate. The corrosion rate is measured using the weight loss method. Micro-photo observations of the S45C steel surface were carried out to determine the type of corrosion. The results demonstrate that the corrosion rate of hardened S45C steel decreases following the longer holding time during hardening. In addition, the corrosion rate of hardened S45C steel decreases when the viscosity of the oil used during hardening is thicker. Finally, the type of corrosion is uniform and pitting corrosion. © International Journal of Modern Manufacturing Technologies.
