Scope

This document defines the grades and the corresponding requirements for spheroidal graphite cast irons.
This document specifies two groups of spheroidal graphite cast iron grades by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. The first group deals mainly with ferritic to pearlitic grades. The second group deals with solid-solution strengthened ferritic grades.
This document also gives an informative classification as a function of hardness.
This document does not apply to the following:
— spheroidal graphite cast irons used for pipes, fittings and accessories which are specified in accordance with ISO 2531 and ISO 7186;
— highly alloyed (austenitic) spheroidal cast irons which are specified in accordance with ISO 2892;
— ausferritic cast irons which are specified in accordance with ISO 17804.
