In the previous report, we tried the tensile tests of the eleven kinds of killed steel plates in each of three directions, i. e. rolling-transverse-and thickness-direction and confirmed that tensile properties in the thickness direction are inferior to other two directions, especially in ductility. In this paper, we studied the directionality of mechanical properties of mild steel and high tension steels. We also studied that of their heat-affected zones and deposited metals by submerged arc welding. From these sxperiments, we knew that; (1) Structural steels, containing high tension-steels, wich are rolled have little ductility in the thickness-direction and near that direction as shown in Figs. 4 (a), 7 (a), 7 (b) and 8. (2) Deposited metals by submerged arc welding have no mechanical directionality in tensile and bending propesties as shown in Figs. 3 (a), 3 (b), and 14. (3) Heat-affected zones have the same mechanical directionality as the parent material.
