Carburization is one of the most popular techniques used by researchers for the heat treatment process, the main function of which is to give focus on carbon abortion in base material. Presented work considered various types of coal by using carburizer. Configuration was made with coal types as based on percentage weight namely; 100%wt lemon, 100%wt charcoal, 100%wt coconut and 33%wt lemon-34%wt charcoal -33%wt coconut as a mixture. The experiment runs subjected by using heavy fuel furnace at 925°C for 11 hours. Focus was given to handless testing, by caring out Vickers hardness test across all the samples. Interesting results were observed with lemon coal which was found to be the best suitable with an effective rise in hardness up to 250 HV (22.1 HRC). Latter with the help of quenching process at 900°C with holding time of 20 min additional improvement was noticed. Finally, considered sample was quenched with Addinol Quenching Oil and the results showed that the sample of lemon coal was the optimum choice among the all the considered samples.
