Armour steel is a medium-carbon steel which is widely used in military and defense industries owing to its ability to protect from projectile and bullet pressure. However, this armour steel still posses mechanical limitation aspect, thus it is needed to engineer for improvement. Therefore, the aim of this research is to undergo mechanical properties engineering by using heat treatment method of austempering within temperature variations of 200, 250, 350, 450, and 500 oC . Experimental results show that austempering process affected to fraction quantity of phase and microstructure of ferrite, pearlite, and bainite. Armour steel resulted by austempering process in temperature 500 oC depicts microstructure transformation and mechanical properties improvement significantly. Microstructure transformation along with proportional fraction volume phases of upper bainite, ferrite, and pearlite highly beneficial to increase impact strength dan ductility of armour steel. Thereby, armour steel resulted by austempering process in temperature 500 oC has thoroughly increased its mechanical properties which capable to be applied in military and defense industries.

Dalam penelitian ini, baja S45C akan diuji dan dibandingkan nilai kekuatan tarik yang dimiliki sebelum dan setelah diberikan perlakuan panas Quench Hardening. Suhu pemanasan yang digunakan dalam proses perlakuan panas ialah 850 ℃, dengan holding time yaitu 30 menit. Media quenching yang digunakan yaitu “Es Batu Ditambah Air”, “Larutan NaCl 3,45%”, dan “Oli SAE 10W-30”. Hasil dari pengujian tarik menunjukkan bahwa media quenching “Es Batu ditambah Air” dan media quenching “Larutan NaCl 3,45%” menghasilkan rata-rata nilai kekuatan tarik 156,27 MPa dan 228,55 MPa, sementara pada raw material dan media quenching “Oli SAE 10W-30” menghasilkan rata-rata nilai kekuatan tarik 707,03 MPa dan 1.116,30 MPa.

Heat treatment is a process of renewing the metal structure by heating the specimen to a temperature below the melting point and a certain time, which is then cooled in a cooling medium to change the physical and mechanical properties. This study aims to determine the effect of quenching media and tempering temperature on the hardness value of DC 11 steel. This study used an experimental method with hardening at 990 °C and a holding time of 30 minutes with quenching media with SAE 10W-30 oil and 3.45 NaCl solution. %. After that, tempering was carried out at 250 °C, 350 °C, and 450 °C with a holding time of 2 hours. Then, the specimens were tested for hardness using the Rockwell method. Based on the results of the study, it was found that the effect with the highest hardness value was found in the quenching media with 3.45% NaCl solution and a tempering temperature of 250 °C of 49.6 HRC. The conclusion obtained is that the higher the tempering temperature, the lower the hardness value.
