Abstract
PURPOSE: To obtain nodular graphite cast iron having a uniform surface hardened layer with high hardness by adding a specified percentage of Cu, Sn or Sb to a basic composition consisting of a specified percentage each of Fe, C, Si, Mn and Mg.
CONSTITUTION: To a basic composition consisting of, by wt., 3.0W4.5% C, 1.5W 3.0% Si, 1.0W1.5% Mn, 0.02W0.08% Mg and the balance Fe is added 0.3W0.8% Cu or 0.03W0.08% Sn and/or Sb or further added about 0.1W0.4% Mo. The resulting nodular graphite cast iron has a small mass effect even if the casting is large in weight, so by carrying out surface hardening as cast, a uniform surface hardened layer with high hardness is obtd., and normalizing is made unnecessary.
