CAST IRON EXCELLENT IN MACHINABILITY AND MECHANICAL PROPERTY

Title:

CAST IRON EXCELLENT IN MACHINABILITY AND MECHANICAL PROPERTY

Document Type and Number:

Japanese Patent JP2002003982

Kind Code:

A

Abstract:

To improve machinability and mechanical properties of cast iron such as flake graphite cast iron, eutectic graphite cast iron and spheroidal graphite cast iron.

This cast iron has a composition containing, by mass, 2.8 to 4.0% C, 1.5 to 2.5% Si, 0.1 to 0.7% Mn, ≤0.1% P, 0.01 to 2.0% Cu, 0.01 to 0.1% Sn and 0.01 to 0.3% S and also containing 0.01 to 1.0% Ti and/or 0.01 to 1.0% Zr, and the balance Fe with inevitable impurities and has a structure in which metallic sulfides and/or metallic multiple carbosulfides are dispersed into an Fe base.
