Hot rolled plate steel as a material to be used for steel armor needs to have the characteristics of a high hardness value. Medium carbon steel as the basic material is quenched at a temperature of 900 oC and tempering is carried out at a temperature of 125 oC and 175 oC with a holding time of 30 minutes. The Ms value is a benchmark for changes in martensite which is influenced by the constituent elements of the material. The use of water as a quench medium changes the structure of austenite to martensite. The martensite structure that occurs increases the optimum hardness value in HRP Steel material. The tempering process carried out above the Ms value causes a decrease in the hardness value. The highest hardness value was obtained in the quenching process with 542 HV which was influenced by the distribution of martensite. The decrease in hardness value occurs due to the tempering process, the average hardness value at temper 125 oC is 524.4 HV and 175 oC is 524 HV.

“…Austenitization at 900 °C and tempering at 125 °C contribute to a substantial effect on the hardness of Q&T Steel [16], and the closest temperature to Ar 3 produced fine austenite. The water quenching of fine austenite provides the fine martensite, reduces the friction coefficient, and is suitable for wear resistance component (armor steel) [1]. The hardness fluctuation occurred (Fig.…”

Quenched and tempered steels are needed for highly-stressed structures in military and non-military equipment. This paper was written for studying the structure and properties (hardness and impact energy absorbed) of medium-carbon and carbon-manganese steels before and after Quench+Temper and Double Quenched+Tempered. Because water is cheap and easy to control, it was used as a quenching medium. This study compares the hardness and impact energy absorbed of quenched plus tempered and double quenched plus tempered steels. The results showed that double quenched plus tempered steel hardness was higher than in quenched plus tempered steels. Besides, the grain structure is refiner than that of quenched plus tempered steel. The taking of the austenite temperature and holding time is essential because of the hardness at the end of the quenching process. The study aims to obtain hardness and impact energy from quenching+tempering and double quenching+tempering of medium-carbon and carbon-manganese steel for armor steel. In the first step, five specimens were heated at 900 o C (held for 30 minutes), cooled in freshwater and produced Q900 Steel. Then, these specimens were heated at 750 o C, 800 o C, 850 o C, and 900 o C, held for 30 minutes and provided Q900+750 Steel, Q900+800, Q900+850 Steel, and Q900+900 Steel. These specimens were tempered at 150 o C (held for 30 minutes) and produced Q900+750&T Steel, Q900+800&T Steel, Q900+850&T Steel, Q900+900&T Steel. Martensite reached the cooling period 357 o C to 182 o C, tempered at 150 o C (held for 30 minutes). Hardness for double-quenching and tempering is higher than for conventional. The maximum impact energy of double-quenching and tempering heat treatment of Q900+850&T steel is suitable for armor steel used
