Founding - Spheroidal graphite cast irons

Scope

This European Standard defines the grades and the corresponding requirements for spheroidal graphite cast irons.
This European Standard specifies 3 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. The third group deals with the interconnected ferritic-pearlitic grades.
This European Standard does not cover technical delivery conditions for iron castings (see EN 1559-1 [3] and EN 1559-3 [4]).
This European Standard does not cover:
— ausferritic spheroidal graphite cast irons which are specified in EN 1564 [5];
— low alloyed ferritic spheroidal graphite cast irons which are specified in EN 16124 [6];
— continuous cast iron bars which are specified in EN 16482 [7];
— austenitic cast irons which are specified in EN 13835 [8];
— spheroidal graphite cast irons used for pipes, fittings and their joints which are the subject of EN 545 [9], EN 598 [10] and EN 969 [11];
— the grades of spheroidal graphite cast irons as specified in EN 545 which are used for products such as industrial valves, non-industrial manually operated shut-off valves and flanges and their joints, which are the subject of the applicable European product standards.
