Microstructure of cast irons - Graphite classification by visual analysis1 Scope This document specifies a method of classifying the microstructure of graphite in cast irons by comparative visual analysis. The purpose of this document is to provide information about the method of graphite classification. It is not intended to give information on the suitability of cast iron types and grades for any particular application. The particular material grades are specified mainly by mechanical properties and, in the case of
