Abstract

The easiest and most frequently used way to increase the surface hardness of the steel while maintaining its inner ductility is the Pack Carburizing process. By using a carburizer from candlenut shell charcoal as a carbon source, sodium carbonate as a catalyst and SAE 20 oil as a cooling medium. The research variables were T1 = 850o C, T2 = 900o C, T3 = 950o C, T4 = 1000o C while the holding time used was 120 minutes. The highest hardness from the research results was found at T3 900o C = 543.8 HV followed by T2 950o C = 542.8 HV, T1 850o C = 529.2 HV, and T4 1000o C = 527.4 HV
