Description
Summary:The purpose of this research is to find an alternative to Steel-making base materials. In this research, the first step was taking material preparation into a specimen test. The specimen test was divided into two parts. The first test was hot forging material as raw material, and the second test was hot forging material with heat treatment process at an austenitization temperature of 950 °C held for 45 minutes (hardening process), then quenched with quench media variations in the form of water, oil, and air. The specimen tests were tempered in a temperature variation of 100 °C, 200 °C, and 300 °C for 45 minutes. Furthermore, raw material specimens and heat-treated specimens were tested for their hardness, tensility, impact, and metallography characterization. The highest value of hardness was obtained in the air specimen with a tempering temperature of 200 °C whose hardness is 612 HV. Because the hardness is above 600 HV, it meets the requirements of 600T Armox steel hardness.
