In the past, we had investigated the number of 1412 steel on the basis of the mill sheet in order to clarify these steel quality, and these steel of mechanical properties, impact property and chemical compositions had been shown[1][2]. We also had discussed the relationship between mechanical properties(tensile strength, yield strength) and chemical compositions[3]. However, in these papers, the relationship between impact property and chemical compositions had not been discussed. In this paper, we investigated the relationship between impact property(Charpy absorbed energy) and chemical compositions(Carbon, Silicon, Manganese, Phosphorus and Sulfur) including PcM(Cracking Parameter of Material) and Ceq(Carbon equivalent), and these results were shown.
