Medium carbon steel is a steel with a carbon content between 0.3% - 0.6%. In its use as a material to produce machine components such as shafts, gears and so on. This category of steel offers a balance between the ductility and formability of low-carbon steels as well as the strength and hardness of high-carbon steels. Corrosion is considered a detrimental process to carbon steel material, the presence of corrosion can accelerate the deterioration of the quality and ability of carbon steel. For this reason, this study aims to describe the type of corrosion that occurs in medium carbon steel (ST 60) and how the corrosion rate affects the hardness of medium carbon steel (ST 60). In this study, medium carbon steel of the ST 60 type was used. The variations of the corrosion medium used are 10% sulfuric acid solution and 10% sodium chloride solution, while for the variation of immersion time is 72 hours, 144 hours and 216 hours. The test parameters of this study are corrosion rate testing and hardness test. Data processing was analyzed using two-way variance analysis. The lowest corrosion rate was obtained in all specimens by immersion in sodium chloride solution. Meanwhile, the highest corrosion rate was obtained in all specimens by immersion in sulfuric acid solution. The highest hardness value was obtained in specimens without immersion corrosion test, followed by all specimens in sodium chloride immersion and the lowest hardness value was obtained in all sulfuric acid immersion test specimens.
