Selected Raw Material Requirements for Japan's Specialty Steel Industry

摘要

Although Japan is a major producer of crude steel, it is poor in industrial raw materials. This Bureau of Mines report describes Japan's raw material needs for chromium, cobalt, manganese, nickel, and tungsten to produce ferroalloys and alloy steels. Japanese imports of these ores or metals by quantity and source are given for 1972-81, inclusive, to indicate (1) the changes in the consumption and supply pattern, and (2) the degree of Japan's dependence on foreign sources. This report also describes measures implemented by Japan to reduce the risk of supply interruption, and discusses the possible implications of supply shortages.
