Microstructure and Mechanical Properties of Pack Carburized AISI 1020 Steel Using Na2CO3 and CaCO3 Catalysts

AISI 1020 steel is categorized in low carbon which widely used for automotive parts industry and construction because its characteristic like high ductility, relatively hardness value, formability. In continuously usage long time, this tends to be worn down surface value. The congruity wear resistance of steel. research, the experimental method pack carburizing process was carried out by heating samples packed along charcoal with catalysts variation Na2CO3 CaCO3 till temperature 900 oC hold it 4 hours effect diffusion mechanism treatment. Thereupon, fast cooled using distilled water. selection different catalyst according capability will expected enhance steel’s microstructure mechanical properties. From obtained that carburized possesses significant transformation affect highest value increment (505,4 HV) lowest rate decrease (0,00821 mm3/minute). Thereby, also exhibits good so can lifetime.
