WebHexavalent chromium [Cr (VI)] is one of the valence states (+6) of the element chromium. It is usually produced by an industrial process. Cr (VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. Chromium metal is added to alloy steel to increase hardenability and corrosion resistance.
