抄録

Effects of sulfides on the tensile, notch impact and fatigue properties of twelve samples of 3%Ni-Mo-V steels, having four different sulfur contents and three forging rates, were investigated. The test results were as follows; (i) the decrease of transverse ductility is proportionate to the forging rate and sulfur content; (ii) the effect of small amount of sulfur on the longitudinal notch toughness is remarkable; (iii) the anisotropy of endurance strength increases with the sulfur content, and the transverse strength of the most dirty (0.090%S) steel is 73% of the longitudinal strength; and (iv) no general relationship could be established between the mechanical properties and the inclusion counts by the usual method.
