Abstract

PURPOSE: To increase the tensile strength, elongation and impact value by adding a prescribed percentage of C, Si, Mn and Ni to Fe so that the C, Si and Ni contents satisfy a specified equation.
CONSTITUTION: This spheroidal graphite austenite cast iron consists of, by wt., 1,7W3.8% C, 0.8W4.5% Si, 1.0W6% Mn and 10W30% Ni while satisfying an equation C(%)+[0.172-0.054.Si(%)]Ni(%)≤7.08-1.55.Si(%) with respect to the C, Si and Ni contents. Graphite of this cast iron is almost perfectly spheroidal, and the iron has high tensile strength and a high impact value.
