  Définition

  A non-piping steel in which no observable gas evolution takes place, but where sufficient gas is formed during solidification to balance or offset the normal shrinkage of the solidifying metal; numerous blowholes are produced and so the central shrinkage cavity of pipe is prevented or considerably reduced in extent. Balanced steels are only partially deoxidized.
