Two layers-laminated plates of 2.5% nickel steel-mild steel and 9% nickel steel-mild steel were made by hot rolling. The relative thickness of the nickel steels was varied from 0.1 to 0.6. And their impact and mechanical properties were examined depending on the relative thickness. The results obtained are as follows : (a) The impact values of these laminated plates stceply increased with a small increase of the 2.5% or 9% nickel steel thickness as compared with the impact value of mild steel. (b) The impact value of the laminated plate of 9% nickel steel is larger than that of stainless steel or 2.5% nickel steel. (c) The tensile strength of the laminated plates linearly increased with an increase of the relative thickness of nickel steel, but their ductility had no linear relation to the relative thickness.
