Abstract

PURPOSE: To manufacture a product having excellent machinability, by quenching spheroidal graphite cast iron having pearlite matrix structure of specific component from A1 transformation range by oil or air cooling to form fine mixed structure consisting of two phases, ferrite and martensite.
CONSTITUTION: The matrix consists of 3.1W4.1% C, 2.1W3.2% Si, ≤1.0% Mn, ≤0.15% P, ≤0.03% S, and one or more members among Cu, Ni, Mo in quantities ≤1.5% Cu, ≤2.5% Ni, and ≤0.5% Mo. The elements for spheroidizing graphite is ≤0.1% one or more members among Mg, Ca, Ce, and Y, the balance being Fe and inevitable impurities. Matrix contg. ≥75% area ratio of pearlite is heated to form a structure where ferrite, austenite, and graphite coexist, then quenched to convert the austenite into martensite to form a matrix of mixed structure composed of ferrite and martensite having ≤15μ mean crystal particle diameter. The matrix is tempered to the structure where graphite is crystallized in the matrix of fine structure consisting of ferrite and tempered martensite or tempered troostite.
