It was intended that metallic materials equivalent or superior to the 110-kg nickel-chromium steels would be made from elements of the domestic resource. The elements Cr, Mn and Mo were thought most efficient among elements of the domestic resource, in so far as the mechanical properties and the mass effect in quenching were concerned. From this viewpoint, chromium-manganese or chromium-manganese-molybdenum steels were prefered and studied, which were found having properties equivalent or superior to the 110-kg nickel-chromium steels. These steels, containing approximately 0.05% C, 1.0∿2.5%, Mn, 7.0∿9.0% Cr, and balance Fe (or 0.05% C, 1.0∿2.5% Mn, 5.0∿7.0% Cr, 0.3∿0.5% Mo and balance Fe), were recommended for applications where heretofore the 110-kg nickel-chromium steels had been used as structural parts.
