Chromium processing - Chromium processing - The metal and its alloys: By far the greatest use of chromium is as a ferrochromium alloying agent in steel manufacture. Pure chromium is added to nonferrous alloys and is also applied as a corrosion-resistant surfacing for other metals. Chromium surfaces are produced on other metals by electroplating and chromizing.
