Abstract

This study aims to determine how much influence quenching towards the hardness value of the casting specimens. This study used an experimental method by combining of 2 types of cooling media and holding time during the quenching process by using a cast material specimen with an initial hardness of 188 HN. The results of the study that had been carried out and showed differences of cooling media and holding time that can affect the hardness value of the specimens result from casting that was a very significant increase in specimens towards heat treatment with differences in cooling media. oil cooling media with a holding time of 5 minutes with a hardness of 217 HN, oil cooling media with a holding time of 10 minutes with a hardness of 204 HN, a cooling medium of 5 minutes of solar holding time with a hardness of 223 HN, a cooling medium for solar holding time of 10 minutes with a hardness of 216 HN.
