Founding - Spheroidal graphite cast irons

This European Standard defines the grades and the corresponding requirements for spheroidal graphite cast irons.
This European Standard specifies 2 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.
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 [7];
-   low alloyed ferritic spheroidal graphite cast irons which are specified in EN 16124 [8];
-   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 [11], EN 598 [12] and EN 969 [13];
-   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.

Additional information on solid solution strengthened ferritic spheroidal graphite cast irons A.1 General This annex applies to solid solution strengthened ferritic spheroidal graphite cast iron grades as specified in Table 3. A.2 Material constitution A.2.1 Chemical composition In order to fulfil the requirements for the mechanical properties, a ferritic structure solid solution strengthened by silicon is recommended (see Table A.1). Table A.1 — Guidance values for silicon content Designation Silicon % approx. a, b Symbol Number EN-GJS-450–18 5.3108 3,20 EN-GJS-500–14 5.3109 3,80 EN-GJS-600–10 5.3110 4,20 a Silicon content may be lower due to other alloying elements or for thick sections. b With increasing silicon content, the carbon content should be decreased correspondingly. A.2.2 Matrix microstructure The matrix should be predominantly ferrite with a maximum pearlite content of 5 %. The amount of free cementite should not exceed 1 %. A.2.3 Graphite morphology The graphite morphology should be mainly of form V and VI in accordance with EN ISO 945-1. Due to the increased silicon content, solid solution strengthened ferritic spheroidal graphite cast irons may show graphite deviations (from forms V and VI) in thick sections. However, ferritic matrices are, also for higher levels of solution strengthening by silicon, much less sensitive to reduced nodularity than cast irons strengthened by substantial amounts of pearlite. A proportion of form III can be accepted, provided the remainder is mainly of form V and VI, to fulfil the minimum tensile properties specified in this European Standard. SIST EN 1563:2018
