  1. Registro 1

    Chromite (FeCr2O4) is the sole commercial ore of chromium, essential for stainless steel, superalloys, chrome plating, and refractories, with no substitute in stainless steel.

  2. Registro 2

    In 1913 Harry Brearley in Sheffield, England discovered that adding roughly 13% chromium to steel produced an alloy that resisted rust - the world's first stainless steel.

  3. Registro 3

    The name "chromium" derives from the Greek word "chroma" meaning color, because nearly all chromium compounds display vivid colors: greens, reds, oranges, and yellows.
