The Effect of Austenitizing Temperature of High Carbon Steel on Hardness And Electrical Conductivity

Abstract

In this study, the importance of the mechanical and electrical properties of high-carbon steel was highlighted due to its wide industrial applications. The aim of the research was to investigate the effect of heat treatment at the austenitization temperature on the hardness and electrical conductivity of high-carbon steel. To achieve this, six samples of high-carbon steel were heat-treated using an electric furnace at a temperature of 950°C, followed by cooling using different methods. Hardness and electrical conductivity tests were conducted on the samples before and after heat treatment. The results showed a significant impact of the heat treatment, with an increase in hardness due to the formation of martensite during water quenching, and a noticeable improvement in electrical conductivity with annealing cooling.
