Steel \Steel\, v. t. [imp. & p. p. {Steeled}; p. pr. & vb. n.
   {Steeling}.] [AS. stlan: cf. Icel. st[ae]la. See {Steel}, n.]
   1. To overlay, point, or edge with steel; as, to steel a
      razor; to steel an ax.

   2. To make hard or strong; hence, to make insensible or
      obdurate.

            O God of battles! steel my soldier's hearts. --Shak.

            Why will you fight against so sweet a passion, And
            steel your heart to such a world of charms?
                                                  --Addison.

   3. Fig.: To cause to resemble steel, as in smoothness,
      polish, or other qualities.

            These waters, steeled By breezeless air to smoothest
            polish.                               --Wordsworth.

Steel \Steel\, n. [AS. st[=e]l, st[=y]l, st[=y]le; akin to D.
   staal, G. stahl, OHG. stahal, Icel. st[=a]l, Dan. staal, Sw.
   st[*a]l, Old Prussian stakla.]
   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.

   2. An instrument or implement made of steel; as:
      (a) A weapon, as a sword, dagger, etc. ``Brave Macbeth . .
          . with his brandished steel.'' --Shak.

                While doubting thus he stood, Received the steel
                bathed in his brother's blood.    --Dryden.
      (b) An instrument of steel (usually a round rod) for
          sharpening knives.
      (c) A piece of steel for striking sparks from flint.

   3. Fig.: Anything of extreme hardness; that which is
      characterized by sternness or rigor. ``Heads of steel.''
      --Johnson. ``Manhood's heart of steel.'' --Byron.

   4. (Med.) A chalybeate medicine. --Dunglison.

   Note: Steel is often used in the formation of compounds,
         generally of obvious meaning; as, steel-clad,
         steel-girt, steel-hearted, steel-plated, steel-pointed,
         etc.

   {Bessemer steel} (Metal.) See in the Vocabulary.

   {Blister steel}. (Metal.) See under {Blister}.

   {Cast steel} (Metal.), a fine variety of steel, originally
      made by smelting blister or cementation steel; hence,
      ordinarily, steel of any process of production when
      remelted and cast.

   {Cromium steel} (Metal.), a hard, tenacious variety
      containing a little cromium, and somewhat resembling
      {tungsten steel}.

   {Mild steel} (Metal.), a kind of steel having a lower
      proportion of carbon than ordinary steel, rendering it
      softer and more malleable.

   {Puddled steel} (Metal.), a variety of steel produced from
      cast iron by the puddling process.

   {Steel duck} (Zo["o]l.), the goosander, or merganser. [Prov.
      Eng.]

   {Steel mill}.
      (a) (Firearms) See {Wheel lock}, under {Wheel}.
      (b) A mill which has steel grinding surfaces.
      (c) A mill where steel is manufactured.

   {Steel trap}, a trap for catching wild animals. It consists
      of two iron jaws, which close by means of a powerful steel
      spring when the animal disturbs the catch, or tongue, by
      which they are kept open.

   {Steel wine}, wine, usually sherry, in which steel filings
      have been placed for a considerable time, -- used as a
      medicine.

   {Tincture of steel} (Med.), an alcoholic solution of the
      chloride of iron.

   {Tungsten steel} (Metal.), a variety of steel containing a
      small amount of tungsten, and noted for its tenacity and
      hardness, as well as for its malleability and tempering
      qualities. It is also noted for its magnetic properties.
