On heating steels containing four different carbon contents at 800°, 900°or 1000°with different packing materials, the conditions of carburization or decarburization of steels were studied. When the carbon content in steels exceeds about 0.5 percent, the decarburization takes place at 800°on heating with carbon powder, though it is prevented by mixing carbonate. If the air penetrates through the packing material during heating, the decarburization is conspicuous. The carburization is markedly energized by adding sodium carbonate, besides barium crabonate. When the carbon content in steel is more than that corresponding to the Acm point, the rate of carburization is very sluggish, even in the case in which a powerful carburizing agent is used. The presence of a small amount of moisture in the carbon powder tends to promote the carburization, while the size of the carbon powder seems to be practically no effect provided it is fine within a certain limit.
