The auther deals, in this paper, with the effects of Carbon and manganese on the yielding point and the impact resilience of our basic open-hearth steel as rolled. The results of the present investigation may be summarized as follows. The effect of manganese on the yielding point of steel increases with the increase of the carbon content, but it is slight, comparing with that on the tensile strength. The impact resilience of steel under the same amount of carbon decreases with the increase of the manganese content. So far as the relations between chemical compositions and physical properties of steel are concerned, under the same tensile strength, the low carbon and high manganese steel raises the yielding point, the elongation and the impact resilience of steel. The relation between chemical composition and yielding point of our basic open-hearth steel as rolled may be expressed by the fallowing empirical formura. Y=0.15C+0.0009C Mn+0.11 Mn+19.5 Where ; Y=Yielding point in kg/mm^2 C=Carbon content in %×100 Mn=Manganese content in %×100
