EN 1563:2011 (E) 4 Introduction The properties of spheroidal graphite cast irons depend on their structure. Spheroidal graphite cast irons covered by this European Standard are divided in two groups: 1) ferritic to pearlitic spheroidal graphite cast irons which were in the previous standard; 2) solid-solution strengthened ferritic spheroidal graphite cast irons which were not in the previous standard. The two groups present specific properties, for example:  the ferritic grades of the first group present the highest impact energy;  the pearlite containing grades are more suitable for wear resistance applications;  the solid-solution strengthened ferritic grades present for an equivalent tensile strength a higher proof strength and a higher elongation than that of the ferritic to pearlitic grades;  a significant property of these solid-solution strengthened ferritic grades is the reduced hardness variation resulting in an improved machinability. The mechanical properties of the material can be evaluated on machined test pieces prepared from:  separately cast samples;  side-by-side cast samples;  cast-on samples;  samples cut from a casting. The material grade is defined by mechanical properties measured on machined test pieces prepared from cast samples. If hardness or un-notched impact energy are a requirement of the purchaser as being important for the application, then Annex C or Annex I provide means for its determination. It is well known that tensile properties and hardness of spheroidal graphite cast irons are interrelated. When considered by the purchaser as being important for the application, both tensile and hardness properties may be specified. Further technical data on spheroidal graphite cast irons is given in Annexes A, E and F. In this European Standard a new designation system by number, as established in EN 1560:2011 [1], is given. NOTE This designation system by number is based on the structure and rules of EN 10027-2 [2] and so corresponds with the European numbering system for steel and other materials. Some spheroidal graphite cast iron grades can be used for pressure equipment. The permitted material grades of spheroidal graphite cast iron for pressure applications and the conditions for their use are given in specific product or application standards. For the design of pressure equipment, specific design rules apply. Annex ZA gives information relating to the conformance of permitted spheroidal graphite cast iron grades to the Pressure Equipment Directive 97/23/EC. SIST EN 1563:2012



EN 1563:2011 (E) 5 1 Scope 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 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 all aspects of:  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];  austenitic cast irons which are specified in EN 13835 [7];  spheroidal graphite cast irons used for pipes, fittings and their joints which are the subject of EN 545 [8], EN 598 [9] and EN 969 [10];  the grades of spheroidal graphite cast iron 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 1563:2011 (E) 7 5 Order information The following information shall be supplied by the purchaser: a) the number of this European Standard; b) the designation of the material; c) the relevant wall thickness; d) any special requirements. All requirements shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order (e.g. technical delivery conditions according to EN 1559-1 and EN 1559-3). 6 Manufacture The method of producing spheroidal graphite cast irons and their chemical composition shall be left to the discretion of the manufacturer who shall ensure that the requirements of this European Standard are met for the material grade specified in the order.  ferritic to pearlitic spheroidal graphite cast irons. For these grades, the level of the mechanical properties is determined by the ferrite to pearlite ratio. This ratio is normally adjusted by alloying with pearlite stabilising elements or, less commonly, by heat treatment.  solid-solution strengthened ferritic spheroidal graphite cast irons. For these grades, the level of the mechanical properties is determined by the extent of solid solution strengthening of the ferritic matrix. This extent is normally governed by the silicon content. NOTE For spheroidal graphite cast irons to be used in special applications, the chemical composition and heat treatment may be the subject of an agreement between the manufacturer and the purchaser. All agreements between the manufacturer and the purchaser shall be made by the time of the acceptance of the order. 7 Requirements 7.1 General The property values apply to spheroidal graphite cast irons cast in sand moulds or moulds of comparable thermal behaviour. Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods. The material designation is based on the minimum mechanical properties obtained in cast samples with a thickness or diameter of 25 mm. The designation is irrespective of the type of cast sample. Mechanical properties are wall thickness dependant as shown in Tables 1, 2 and 3. For relevant wall thicknesses more than 200 mm, the manufacturer and the purchaser shall agree on the minimum values to be obtained and the type and size of the cast sample. NOTE Tensile testing requires sound test pieces in order to guarantee pure uni-axial stress during the test. SIST EN 1563:2012

Several types of samples (separately cast samples, cast-on samples, side-by-side cast samples, samples cut from a casting) can be used, depending on the mass and wall thickness of the casting. When relevant the type of sample should be agreed between the manufacturer and the purchaser. Unless otherwise agreed the choice of the option is left to the discretion of the manufacturer. When the mass of the casting exceeds 2 000 kg and its relevant wall thickness 60 mm, cast-on samples or side-by-side samples should preferably be used; the dimensions and the location of the sample shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order. If the spheroidizing treatment is carried out in the mould (in-mould process), the separately cast sample should be avoided. All samples shall be adequately marked to guarantee full traceability to the castings which they represent. The samples shall be subject to the same heat treatment, as that of the castings they represent, if any. Tensile and impact test pieces shall be finally machined from the samples after the heat treatment. SIST EN 1563:2012
