Abstract :
This research was conducted to find out the influence of heat treatment temperature variations and variations with a detention time with the aim to find out how temperature and how long the detention the right to increase the hardness of the steel, with using a single cooling media namely media water cooling solution of salt, after doing the process of heating (Heat Treatment) on specimens with temperature variations i.e. temperature 750 ° C, 800 ºc, 850 ° C and 900 ° C, and was detained by a detention time of two (the Holding Time) i.e. 15 minutes and 30 minutes, found the value of hardness on each specimen to rise and the value of the highest violence obtained at a temperature of 800 ° C with a detention time of 15 minutes, with the HRC hardness value of 64.2, while the lowest value was obtained at a temperature of 800 ° C with detention time of 30 minutes, with a value of HRC 51.6, from research that has been done then obtainable temperature to increase violence a good temperature is 800 ° C with detention time 15 minutes.
