ABSTRACT:
A cast iron slide member is formed from cast iron comprising 3.0% to 3.6% by weight of carbon (C), 1.6% to 2.4% by weight of silicon (Si), 0.2% to 1.5% by weight of manganese (Mn), 0.5% to 1.5% by weight of chromium (Cr), 1.5% to 3.0% by weight of nickel (Ni), 0.5% to 1.0% by weight of molybdenum (Mo), 0.0003% to 0.1% by weight of at least one chilling promoting element E.sub.L selected from the group consisting of bismuth (Bi), tellurium (Te) and cerium (Ce), and the balance of iron (Fe) and unavoidable impurities. The slide member has a chilled slide portion. Thus, it is possible to improve the scuffing and pitting resistances of the slide portion.
