EN 16482:2014 (E) 3 Foreword This document (EN 16482:2014) 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of an identical text or by endorsement, at the latest by December 2014 and conflicting national standards shall be withdrawn at the latest by December 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. Within its programme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 7 “Spheroidal graphite, silicon molybdenum and ausferritic cast iron” to prepare the following standard: EN 16482, Founding — Continuous cast iron bars 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, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16482:2014 (E) 4 Introduction The European Standards EN 1561 [4] and EN 1563 [5] classify grey cast irons and spheroidal graphite cast irons respectively, which are cast in sand moulds or moulds of comparable thermal behaviour. This European Standard classifies grey cast iron and spheroidal graphite cast iron bars, which are produced by the continuous casting process. Due to the high cooling rate during solidification and further cooling, both graphite and matrix structure differ from those obtained by sand casting and consequently the mechanical properties in relation to section thickness [8], [9]. The mechanical properties of continuous cast iron bars are evaluated on machined test pieces prepared from samples cut from the bars. However, for many applications tensile strength or hardness are not the only interesting or determining properties. Other mechanical or physical properties can be decisive for the use of grey cast iron or spheroidal graphite cast iron, for example: thermal capacity, thermal diffusivity, damping capacity, thermo-cycle fatigue and toughness. Additional technical data for grey cast irons is given in EN 1561 and for spheroidal graphite cast irons in EN 1563 and Annex D of this European Standard. SIST EN 16482:2014

EN 16482:2014 (E) 7 For the cast irons to be used in special applications, the chemical composition and the 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 Characterizing properties The order shall specify in an unambiguous manner whether the tensile strength measured on a test piece machined from samples cut from the continuous cast bars or the Brinell hardness measured on the bars is the characterizing property. If it does not do so, then the manufacturer shall characterize the material according to tensile strength. 7.2 Tensile properties 7.2.1 General The property values apply to grey cast iron and spheroidal graphite cast iron bars produced by the continuous casting process. Tensile properties are dependant of the bar diameter as shown in Table 1 and Table 2. For rectangular bars, the corresponding diameter D for the determination of the minimum tensile properties shall be calculated with Formula (1): ()()BHBHD+××=2 (1) where D is the corresponding bar diameter in millimetres (mm); H is the height of the bar in millimetres (mm); B is the width of the bar in millimetres (mm). NOTE Tensile testing requires sound test pieces in order to guarantee pure uni-axial stress during the test. For bar diameters > 400 mm, the minimum tensile properties to be obtained shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order. 7.2.2 Test pieces machined from samples cut from the bar The tensile properties, when measured in accordance with 9.1 using test pieces machined from samples cut from the bar, shall be in accordance with the requirements of Table 1 for grey cast irons or Table 2 for spheroidal graphite cast irons.

FprEN 16482:2013 (E) 4 Introduction The European Standards EN 1561 [1] and EN 1563 [2] classify grey cast irons and spheroidal graphite cast irons respectively, which are cast in sand moulds or moulds of comparable thermal behaviour. This European Standard classifies grey cast iron and spheroidal graphite cast iron bar, which are produced by the continuous casting process. Due to the high cooling rate during solidification and further cooling, both graphite and matrix structure differs from those obtained by sand casting and consequently the mechanical properties in relation to section thickness [3] [4]. The mechanical properties of continuous cast iron bars are evaluated on machined test pieces prepared from samples cut from the bar. However, for many applications tensile strength or hardness are not the only interesting or determining properties. Other mechanical or physical properties can be decisive for the use of grey cast iron or spheroidal graphite cast iron, for example: thermal capacity, thermal diffusivity, damping capacity, thermo-cycle fatigue and toughness. Additional technical data for grey cast irons is given in EN 1561 and for spheroidal graphite cast irons in EN 1563 and Annex D of this European Standard. kSIST FprEN 16482:2014
FprEN 16482:2013 (E) 5 1 Scope This European Standard defines the grades of grey cast iron and spheroidal graphite cast iron bars, which have been manufactured by the continuous casting process. This European Standard specifies the characterizing properties of grey cast iron bars by either a) the tensile strength measured on machined test pieces prepared from samples cut from the bars or b) the hardness measured on the bars. If agreed by the manufacturer and the purchaser, the combination of both tensile strength from option a) and hardness from option b) may be specified. This European Standard specifies the characterizing properties of spheroidal graphite cast iron bars by the tensile strength measured on machined test pieces prepared from samples cut from the bars. This European Standard specifies four grades of grey cast iron and 14 grades of spheroidal graphite cast iron by a classification based on tensile strength and four grades of grey cast iron by a classification based on Brinell hardness. This European Standard specifies also the straightness of the bars.

NOTE The designation system is specified in EN 1560 [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 dimensions of the bar; 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 methods of producing grey cast iron and spheroidal graphite cast iron continuous cast bars and their chemical compositions, 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. kSIST FprEN 16482:2014
FprEN 16482:2013 (E) 7 For the cast irons to be used in special applications, the chemical composition and the 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 Characterizing properties The order shall specify in an unambiguous manner whether the tensile strength measured on a test piece machined from samples cut from the continuous cast bars or the Brinell hardness measured on the bar is the characterizing property. If it does not do so, then the manufacturer shall characterize the material according to tensile strength. 7.2 Tensile properties 7.2.1 General The property values apply to grey cast iron and spheroidal graphite cast iron bars manufactured by the continuous casting process. Tensile properties are dependant of the bar diameter as shown in Table 1 and Table 2. For rectangular bars, the corresponding diameter D for the determination of the minimum tensile properties shall be calculated with the Formula (1): ()()BHBHD+××=2 (1) where D is the corresponding bar diameter in millimetres (mm); H is the height of the bar in millimetres (mm); B is the width of the bar in millimetres (mm). NOTE Tensile testing requires sound test pieces in order to guarantee pure uni-axial stress during the test. For bar diameters > 400 mm, the minimum tensile properties to be obtained shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order. 7.2.2 Test pieces machined from samples cut from the bar The tensile properties, when measured in accordance with 9.1 using test pieces machined from samples cut from the bar, shall be in accordance with the requirements of Table 1 for grey cast irons or Table 2 for spheroidal graphite cast irons. kSIST FprEN 16482:2014
