Abstract :
This reseach was conducted to determine the effect of variations in oil and brine
media and temperature variations on the Rockwell hardness of KS steel plate (low
karbon) 6 mm in the heat treatment process.the heat treatment process is widely
used to increase hardness and add carbon elements to steel that has a low
hardness value and needs to be given special treatment to increase the hardness
of the steel. In this study the oil and salt water media.in this study the heat
treatment process was carried out with variations in temperature, namely 7500C,
8000C after reaching the desired temperature and then held for 10 minutes.
Meanwhile, for the Rockwell hardness test, the highest hardness value at 8000C
was found in the brine media with a hardness value of 64,3HRC
