Founding. Ausferritic spheroidal graphite cast irons. Classification

Status : Current   Published : June 2020



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:

  1. separately cast samples, side-by-side cast or cast-on samples;

  2. samples cut from a casting.

This document also specifies two grades by a classification as a function of hardness.
