Abstract
The purpose of this study was to determine the comparison of the hardness value of assab 705 steel and AISI 4140 steel. Steel assab 705 and AISI 4140 steel were two medium carbon steels whose carbon content was 0.38% -0.43% C. With its carbon content the same, allowing these two steels to be hardened by a hardening heat treatment process using oil cooling media. The experimental method was used in this study, with 6 specimens of test specimens and cooled with oil cooling media. The results of the hardness test showed that there was a difference in the value of hardness between steel assab 705 with steel AISI 4140. In assab 705 steel, the average value of steel hardness of the three test specimens obtained a value of 378.33 BHN. Whereas for AISI 4140 steel, the average value of steel hardness from the three test specimens obtained a value of 489 BHN. It can be concluded that Steel AISI 4140 has a higher hardness value than steel assab 705.
