Abstract

PURPOSE: To obtain nodular graphite cast iron having superior toughness and austenite structure and making long-time heat treatment at high temp. unnecessary by reducing the Ni content of nodular graphite cast iron and specifying other components.
CONSTITUTION: This nodular graphite cast iron consists of, by wt., 1.7W3.8% C, 0.8W3.0% Si, 1.0W6.0% Mn, 10.0W22.0% Ni, ≤0.05% S, ≤0.1% Mg, Ca, Ce or other spheroidizing element, and the balance Fe and inevitable impurities. By this composition superior fluidity is provided to enable the manufacture of casting having complex form, and the amount of hot top is reduced, resulting in an enhanced product yield. Since this cast iron has high toughness as cast without adding a special element such as Cu or Cr, long-time heat treatment causing deformation of products and lowering in the dimensional accuracy is made unnecessary. This austenitic nodular graphite cast iron is applied to a material for pump casing, etc. used in a low temp. area.
