CAST IRONS

Alloys of iron, carbon and silicon where carbon is present in excess of the amount which can be retained in solid solution are termed cast irons The common engineering grades contain Carbon in the form of flake graphite, but this can be modified with additions to a spheroidal shape. This imparts major improvements in strength and ductility and the alloys are then called SG, Nodular or Ductile irons (N1-N5).. Additions of nickel and chromium change the structure to produce the wear resisting alloy Ni Hard (Q51-Q52), while higher amounts of these elements yield the excellent corrosion resistance of the Ni Resist Family (R10-R13).
