Chromium has a wide range of uses in the metallurgical, chemical, and refractory industries. It is one of the nation's most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardness and resistance to corrosion or oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important applications. Other applications are in alloy steel, plating of metals, pigments, leather processing, catalysts, and refractories. This Bureau of Mines report presents comprehensive data on chromium including strategic considerations, problems, technology trends, reserves- resources, supply-demand relationships, economic factors and problems, operating factors and problems, and outlook to 2000.
