Abstract
This document defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons.
This document specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties determined on machined test pieces prepared from:
— separately cast samples, side-by-side cast or cast-on samples;
— samples cut from a casting.
This document also specifies two grades by a classification as a function of hardness.
