Founding. Ausferritic spheroidal graphite cast irons1 Scope This European Standard defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons. This European Standard specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. This European Standard also specifies two grades by a classification as a function of hardness. This European Standard
