Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation''s most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important
