Carburizing Process

Increase of soaking time contributed to the effectiveness of case depth formation, hardness properties and carbon content of carburized steel. This paper investigates the effect of different soaking time (7-9 hours) using powder and paste compound to the carburized steel. Low carbon steels were carburized using powder and paste compound for 7, 8 and 9 hours at temperature 1000°C. The transformation of microstructure and formation carbon rich layer was observed under microscope. The microhardness profiles were analyzed to investigate the length of case depth produced after the carburizing process. The increment of carbon content was considered to find the correlation between types of carburizing compound with time. Results shows that the longer carburized steel was soaked, the higher potential in formation of carbon rich layer, case depth and carbon content, which led to better hardness properties for carburized low carbon steel. Longer soaking time, 9 hours has a higher dispersion of carbon up to 41%-51% compare to 8 hours and 7 hours. By using paste carburizing, it has more potential of carbon atom to merge the microstructure to transform into cementite (1.53 wt% C) compare to powder (0.97 wt% C), which increases the hardness of carburized steel (13% higher).

Abstract Stress corrosion cracking (SCC) behavior in 60% Ca(NO3)2, 3% NH4NO3 solution boiling at 110 C is reported for relatively pure 1% Ni, 1% Cr, or 1% Ti steels as a function of carbon content. The steels were water-quenched, cold-rolled, or furnace-cooled. Commercial 4140 steel heat-treated to various hardness levels was similarly tested. It was also subjected to SCC in boiling 3% NaNO3 and boiling 3% NaCl. Critical potentials below which SCC does not occur were measured in 3% NaNO3 for the latter steel at 4 hardness levels. The results are interpreted in terms of stress-sorption cracking.
