In order to get higher strength and toughness of steel weld metal, the effects of single or double addition of alloying elements such as Al, Ni, Cr, Mo or B on the strength and toughness of 0.03-0.05% C as-cast steel specimens in stead of steel weld metal have been investigated. This carbon content made the toughness of as-cast steel specimens containing 0.35% Si and 1.5% Mn highest in previous report. The results obtained as follows; 1 : No single addition of Al, Ni, Cr, Mo or B improve the toughness of as-cast low carbon steel. 2 : Double addition of 0.34% Ni and 0.09% Mo is effective on the improvement of mechanical properties of as-cast steel. In this case, the tensile strength is 46kg/mm, and the impact energy transition temperature is -40℃.
