DIN EN 1563:2012-03EN 1563:2011 (E) 4 Introduction The properties of spheroidal graphite cast irons depend on their structure. Spheroidal graphite cast iron

32、s 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

33、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

34、 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

35、 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 purcha

36、ser 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

37、 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 a

38、nd 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

39、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. DIN EN 1563:2012

40、-03EN 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 tes

41、t 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 Europea

42、n 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 f

43、or 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, whic

44、h are the subject of the applicable European product standards. 2 Normative references The following referenced documents are indispensable for the application of this document.
