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 reqi.arements shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order (e.g. technical delivery conditions accordwig 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 matenal 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 pearhte ratio. This ratio is normally adjusted by alloying with pearlite stabdising 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 matnx. This extent is nomialy governed by the silicon content
NOTE Fcw spheroidal graphite cast Irons to be used In special applications, the chemical cownpos4ion 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 mmimum 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-axisi stress during the test.
7.3.2 T.st pieces machined from samples cut from a casting
If applicable, the manufacturer and the purchaser shall agree on:
the location(s) on a casting where the sample(s) shall be taken;
— the mechanical properties that shall be measured;
— the minimum values, or allowable range of values, for these mechanical properties (for information, see Annex B).
NOTE The propert.es of castings may not be urwform, depending on the conlexity of the caslings and vahation in their section thIcknesses.
7.3.3 Hardness
Brinell hardness and its range values for the grades hsted in Table 3 shall only be specdied when agreed between the manufacturer and the purchaser by the time of acceptance 01 the order.
Information regarding hardness is given in Annex C.
7.3.4 GraphIte structure
The graphite structure shall be mainly of form V and VI in accordance with EN ISO 945-1. A more precise definition may be agreed between the manufacturer and the purchaser.
NOTE 1 A.2.3 gives more nformabon on grhlte structure.
NOTE 2 Annex D gives more liforrnation regardrng nodLdarity.
7.3.5 Matrix structure
Information on matrix structure is given ii Table El and A,2,2.
8 Sampling
8.1 General
Samples shall be made from the same material as that used to produce the casting(s) which they represent.
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 op(ion is left to the discretion of the manufacturer.
When the mass of the casting exceeds 2000 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 (li-mould process), the separately cast sample should be avded.
All samples shall be adequately marked to guarantee full traceabllity 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.
