Study Experimental the Effect of Normalizing Treatment and Galvanic Pack Carburizing Process on Mechanical Properties of Low Carbon Steel

Steel is the type of metal most often used in engineering. This study aimed to improve mechanical properties mild steel terms hardness, ductility, and other compare hardness carburized by galvanic treatment with non-galvanic carburizing steel. research was carried out varying heat process, namely without galvanic, where process uses activated carbon coconut shell charcoal a weight percentage 80% 20% K2CO3 (Potassium Carbonate) at temperature 9000C holding time 60 minutes, 120 minutes 180 minutes. The results obtained from this indicate that (hardness) increase 1 hour on heating method better value than method. 94.06 HRB, while method, it 76.4 HRB. And pearlite phase formed, increasing surface specimen.
