Abstract : Chromium is a highly strategic and critical metal because of its significant import dependence and its essential uses for defense, energy and industrial products. It is used in such diversified applications as stainless steels and tool steels; alloy steels to provide hardenability in heat treatment, in air frames, and in landing gear; heat and corrosion resistant alloys; superalloys for jet engines; alloy cast iron; electroplating; and corrosion treatment for aluminum alloys. This paper presents information on application areas where substitution and conservation appear feasible in a supply crisis based on present available technology. Likewise, applications where research is needed to expand the substitution potential will be indicated. Opportunities for conservation and displacement with emerging technologies will be discussed. Finally, the value of an organized effort on substitution preparedness to gather and develop information on chromium substitution and conservation technology and have it ready as a contingency plan will be presented.
