Abstract

Carburizing is a case-hardening process by which carbon is added to the surface of lowcarbon steel. This results in carburized steel that has a high-carbon surface and a lowcarbon interior. In this research, studies on the effects of carburizing on mechanical properties of carburized steel were the main objective. Carburizing process was conducted at temperature of 850 °C and time of 6 hours. This research reports the effect of carburizing on mechanical properties, includes the hardness, compression, and tensile strength of low carbon steel. As for comparison data, the surface hardness was in the range of 75.3 HRB to 76.8 HRB. It is however showed significantly higher after carburized with value in the range of97.2 HRB to 99.3 HRB. The stress determine from tensile test before carburized was found to be higher at 531.07 MPa, compared after carburized at 507.44 MPa, respectively. Fortunately the strength shows increment from 467.72 MPa before carburized to 536.30 MPa after carburized. Carburizing process is then continued by annealing and quenching-tempering process to improve the brittleness of specimen and as a precaution to obtain better result. The overall results from the study show that the carburizing process can significantly improve the mechanical properties of Low Carbon Steel. And for this research, result has shown that carburizing increased the surface hardness of low carbon steel.
