Abstract
PURPOSE: To provide tough spherical graphitic cast iron for abrasion resistant parts obtained by compounding C, Si, Mn, P, S, Cu, Ni and a graphite spheroidizing treatment element in a specified ratio.
CONSTITUTION: C; 3.1W4.1%, Si; 2.1W3.5%, Mn; 1% or less, P; 0.15% or less, S; 0.03% or less, Cu; 1.5% or less, Ni; 2.5% or less, and according to necessity, Mo; 0.1W0.5% and one or more kinds selected from a graphite spheroidizing treatment element Mg, Ca, Ce, Y at 0.1% are compounded to obtain the titled cast iron. A base texture is an acicular fine texture having 20W70% of ferrite dispersed therein and an acicular fine texture having 20W70% of ferrite and a two phase mixture of perlite, martensite or sorbite. This texture is obtained by a method wherein a conventional chemical composition or spherical graphitic cast iron containing Ni, Cu, Mo or the like is preliminarily converted to a martensite texture in a cast condition or by heat treatment and heated to an A1 transformation region by rapid heating and held at this temp. and annealed by rapid quenching.
