   1. (Metal) A variety of iron intermediate in composition and
      properties between wrought iron and cast iron (containing
      between one half of one per cent and one and a half per
      cent of carbon), and consisting of an alloy of iron with
      an iron carbide. Steel, unlike wrought iron, can be
      tempered, and retains magnetism. Its malleability
      decreases, and fusibility increases, with an increase in
      carbon.

Bessemer steel \Bes"se*mer steel`\
   Steel made directly from cast iron, by burning out a portion
   of the carbon and other impurities that the latter contains,
   through the agency of a blast of air which is forced through
   the molten metal; -- so called from Sir Henry Bessemer, an
   English engineer, the inventor of the process.
