Abstract

PURPOSE: To allow as cast product to be quickly surface-quenched without preheat treatment by adding one or more of each specific amount of Cu, Sb or Sn, or Mn to a basic composition consisting of each specific amount of C, Si, Mn, Mg, and the remaining Fe.
CONSTITUTION: To a basic composition consisting of C: 3W4.5%, Si: 2W3.5%, Mn<0.9% Mg: 0.02W0.08%, and the remaining Fe, is added one or more of alloy components which are Cu: 0.2W0.8%, Sb or Sn: 0.01W0.05%, and Mo: 0.1W 0.4%. When this cast iron is used as material which needs surface quenching, a wide range of heating condition is allowed for hardening, and therefore good sur face hardness and appropriate hardness depth can be obtained in an easy process control.
