Abstract
The need for metal materials in the industry is currently increasing. However, metal materials that exist today do not fully have the desired properties and characteristics. One that is included in the metal materialis carbon steel. Carbon steel is a metal material that is currently widely used in industry. Carbon steel is widely used in small and medium industries as a construction material. This study aims to determine the effect of holding time variations and quenching variations on the pack carburizing process and to determine the hardness value of carbon steel before and after the pack carburizing process. The method used is experimental research by testing rockwell hardness. Rockwell hardness testing was carried out on 16 specimens by testing 5 points on each specimen using mangrove wood charcoal at a temperature of 900°C with variations in holding times of 30 minutes, 60 minutes, 90 minutes, 120 minutes. The variations of cooling media used are sea water, rain water, well water and mineral water. The results showed that the specimens with the highest hardness were specimens that were treated with a holding time of 120 minutes with sea water quenching media with a hardness of 83.94 HRA. The hardness before the pack carburizing process was 47.54 HRA after the pack carburizing process was 60.72 HRA to 83.94 HRA.
