Founding - Ausferritic spheroidal graphite cast irons
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 does not cover technical delivery conditions for iron castings, see EN 1559-1  and EN 1559-3 .
NOTE Grades given in Annex A are not intended for pressure equipment applications.
