Scrap-metal
Fragments of cast-metal to be remelted, or of malleable iron. The latter, when reworked in the forge by piling, heating, and rolling, is sometimes converted into the strongest iron by reason of the twisted fibre imparted to the forgings. Cast-iron scrap of good quality forms a good corrective in all mixtures when the resultant casting made from the pig iron in stock would be too soft and graphitic. See MIXING CAST IRON; BUGS; SILICON; SOFTENERS.
