The Impact of Heat Treatment on Hardness and Corrosion Resistance of Medium Carbon Steel

Abstract

The primary aim of this project is to examine the impact of heat treatment processes on the hardness and corrosion resistance of medium carbon steel. In the current study, an experiment is conducted utilizing various devices and materials to assess the impact of heat treatment on the mechanical properties and corrosion resistance of medium carbon steels. The specimens are subjected to tempering at temperatures of 200°C and 400°C for a duration of 1 hour. Following the heat treatment, the samples underwent mechanical testing for hardness (Rockwell), and the corrosion of steel was also examined. The findings indicated a high hardness of 52 HRD as a result of quenching, in contrast to the annealed sample, which exhibited the lowest hardness among all specimens across all types of steel. The outcomes that were achieved indicate that the heat treatment procedure considerably diminished the corrosion behavior of carbon steel during the quenching process, with a weight reduction of merely 0.0322 g.
