Zusammenfassung:PURPOSE:To give the toughness to a brittle white cast iron and to obtain said high strength cast iron by casting a ferroalloy contg. Se in addition to basic components of C, Si, Mn, P to the white cast iron, heat treating said cast iron in nonoxidizing gaseous atmosphere to cut and separate eutectic cementites in as cast state and to change them to particle state of uniform distribution. CONSTITUTION:The ferroalloy contg. 2.0-3.5% C,
