PROBLEM TO BE SOLVED : To improve the high-temperature creep resistance of FCD400 alloy which can be used for a checker-receiving hardware member and the like.
SOLUTION : A heat-resistant spheroidal graphite cast iron having excellent creep resistance, contains, in mass%, C : 3.0%-4.3%, Si : 1.5-3.5%, Mn : 1.0% or less, a graphite spheroidizing agent comprising at least one of Mg, misch metal, Ce, and Ca : 0.010-0.15%, P : 0.20% or less, S : 0.050% or less, Ni : 0.50-1.5%, Cu : 0.20-1.0%, and Mo : 0.50-1.5%, with the balance being Fe and inevitable impurities.
