Chromium | Minerals Education Coalition
Chromium is alloyed (that is, mixed) with steel to make it corrosionresistant or harder. An example is its use in the production of stainless steel, a bright, shiny steel that is strong and resistant to oxidation (rust). Stainless steel production consumes most of the chromium produced annually. Chromium is also used to make heatresisting steel.
