EN 1562:2019 (E) 3 European foreword This document (EN 1562:2019) has been prepared by Technical Committee CEN/TC 190 “Foundry technology”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2019 and conflicting national standards shall be withdrawn at the latest by September 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1562:2012. Within its programme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 6 “Malleable cast iron” to revise EN 1562:2012. This document has been prepared under a standardization request given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Annex C provides details of significant technical changes between this European Standard and the previous edition. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1562:2019
EN 1562:2019 (E) 4 Introduction This document classifies malleable cast irons into two groups. The first group is concerned with decarburized irons referred to as whiteheart malleable cast iron. The second group is non-decarburized irons referred to as blackheart malleable cast iron. Both groups, except completely decarburized whiteheart malleable cast iron, contain free carbon as graphite, called temper carbon. Both groups have grades with structures that can range from ferrite to pearlite and/or other transformation products of austenite. Materials are designated in terms of tensile strength and percentage elongation. Weldablility is an important property of malleable cast irons. Malleable cast irons have good impact resistance and ductility at low temperatures. In this document, a designation system by number, as established in EN 1560 [1], is given. NOTE This designation system by number is based on the principles and the structure as set out in EN 10027–2 [2] and so corresponds with the European numbering system for steel and other materials. Some malleable cast iron grades can be used for pressure equipment. The permitted material grades of malleable 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 malleable cast iron grades to the Pressure Equipment Directive 2014/68/EU. SIST EN 1562:2019
EN 1562:2019 (E) 5 1 Scope This document defines grades and the corresponding requirements for malleable cast irons. This document specifies five grades of whiteheart malleable cast iron and nine grades of blackheart malleable cast iron, based on mechanical properties measured on cast samples (which are test pieces). This document specifies Brinell hardness values determined only when these values are requested by the purchaser. This document does not cover technical delivery conditions for malleable cast iron castings. Reference can be made to EN 1559-1 [3] and EN 1559-3 [4]. This document does not cover chemical composition, except phosphorus (see Clause 6). 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

ISO and IEC maintain terminological databases for use in standardization at the following addresses: — IEC Electropedia: available at http://www.electropedia.org/ — ISO Online browsing platform: available at http://www.iso.org/obp 3.1 malleable cast iron cast material, mainly iron and carbon based, which solidifies in the as-cast condition with a graphite-free (white) structure and achieves its final properties after a heat treatment 3.2 whiteheart malleable cast iron cast material, mainly iron and carbon based, which is cast white and then given a heat treatment in a decarburizing atmosphere to produce a material which is partially or entirely decarburized Note 1 to entry: Any remaining graphite is in the form of temper carbon. SIST EN 1562:2019
EN 1562:2019 (E) 6 3.3 blackheart malleable cast iron cast material, mainly iron and carbon based, which is cast white and then given a non-decarburizing heat treatment, to produce a material in which all graphite is in the form of temper carbon 3.4 primary graphite graphite which precipitates in the flake form during solidification Note 1 to entry: Primary graphite is more correctly referred to as eutectic graphite. 3.5 cast sample quantity of material cast to represent the cast material, including separately cast sample and side-by-side cast sample 3.6 separately cast sample sample cast in a separate sand mould under representative manufacturing conditions and material grade 3.7 side-by-side cast sample sample cast in the mould alongside the casting, with a joint running system 3.8 relevant wall thickness wall thickness representative of the casting, defined for the determination of the size of the cast samples to which the mechanical properties apply 4 Designation The material shall be designated either by a symbol or by a number as given in Tables 1, 2 and 3. NOTE Comparison of EN 1562 grade designations to the grades from ISO 5922:2005 [5] is given in Annex A. 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 of the casting; 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 [3] and EN 1559-3 [4]. SIST EN 1562:2019
EN 1562:2019 (E) 7 6 Manufacture The method of manufacture of malleable cast iron as well as its chemical composition and heat treatment shall be left to the discretion of the manufacturer, who shall ensure compliance with the property requirements given in this document for the material ordered. NOTE To produce structures such as ferrite, pearlite or other transformation products of austenite, both material types (groups) depend upon either the malleablising heat treatment or the subsequent additional heat treatment and/or additions of alloying elements. For castings intended to be given additional treatment (such as galvanizing) and/or in the case of castings for use at low temperatures to optimize the impact resistance of the material, the phosphorus content should not exceed 0,10 %. For malleable cast iron materials to be used in special applications, the chemical composition and any special heat treatment may be the subject of an agreement between the manufacturer and the purchaser by the time of acceptance of the order. 7 Requirements 7.1 General The property values apply to malleable 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, when agreed between the manufacturer and purchaser at the time of acceptance of the order. The material designation is based on the minimum mechanical properties obtained in cast samples with a diameter of 12 mm. Mechanical properties are wall thickness dependent as shown in Tables 1, 2 and 3. 7.2 Tensile strength and elongation The tensile strength and elongation shall be tested in accordance with 9.1, the values of tensile strength and percentage elongation after fracture (hereafter referred to as elongation) shall be in accordance with the requirements specified in Tables 1, 2 and 3. 7.3 0,2 % Proof strength When requested by the purchaser and agreed at the time of acceptance of the order, 0,2 % proof strength shall be determined in accordance with 9.2 and the values shall be in accordance with the requirements specified in Tables 1, 2 and 3. 7.4 Brinell hardness Brinell hardness and its range values shall only be specified when agreed between the manufacturer and the purchaser at the time of acceptance of the order. Guidance values for Brinell hardness are listed in Tables 1, 2 and 3. The method of testing and sampling shall be agreed in accordance with the method specified in 9.3. 7.5 Impact energy Impact energy testing is normally requested for EN-GJMB-350-10 only. The method of testing shall be in accordance with 9.4. If the purchaser requires impact testing to be performed on other grades of malleable cast irons, then the Charpy un-notched test should be used (see informative Annex B). SIST EN 1562:2019
EN 1562:2019 (E) 8 For the malleable cast iron grades intended for uses covered by pressure equipment European legislation, the impact energy shall be determined in accordance with 9.4.
