One of the authors found a new phenomenon that very fine eutectic graphites were. formed in the cast iron when it was produced after it was made contact in liquid state with a slag containing a limited quantity of TiO_2. This special cast iron was called "S-H cast iron." The present experiments were carried out to compare various mechanical properties of S-H cast iron to those of common gray cast iron having the same composition as the former. The results obtained were as follows : Within the limit of the present investigation, tensile and transverse strengths of S-H cast iron were higher than those of common gray cast iron in the range of carbon content higher than 3.3%. In the lower range of carbon content the relation was reversed. In general, S-H cast iron had smaller value in deflection and far higher value in Brinell hardness than the common gray cast iron.
