12 EN :2004 (E) 7 Requirements 7.1 Generl The following requirements pply when smpling, preprtion of test pieces nd testing specified in Cluses 8, 9 nd 10 re crried out. 7.2 Chemicl composition The chemicl composition determined by ldle nlysis shll comply with the specified vlues of Tbles 2 nd The upper limits pplicble for the product nlysis re given in Tbles 4 nd 5. The product nlysis shll be crried out when specified t the time of the order. See option The mimum crbon equivlent vlues for the grdes S235, S5, S355 nd S450, bsed on the ldle nlysis, given in Tble 6 shll pply. For the crbon equivlent vlue formul see of EN : For ll S235, S5 nd S355 qulities the following dditionl chemicl requirement cn be greed t the time of the order: Coppercontent between 0,25 nd 0,40 on ldle nlysis nd between 0,20 nd 0,45 on product nlysis. In this cse the mimum crbon equivlent vlue of Tble 6 shll be incresed by 0,02. See option When products of grde S5 nd S355 re supplied with control on Si e.g. for hotdip zinccoting so tht there could be need to increse the content of other elements like C nd Mn to chieve the required tensile properties, the mimum crbon equivlent vlues of Tble 6 shll be incresed s follows: for Si 0,030, increse CEV by 0,02 ; for Si 0,25, increse CEV by 0, Mechnicl properties Generl Under the inspection nd testing conditions s specified in Cluses 8, 9 nd 10 nd in the delivery condition s specified in 6.3 the mechnicl properties shll comply with the vlues given in Tbles 7, 8 nd For products ordered nd supplied in the normlized or normlized rolled condition (see 6.3) the mechnicl properties shll comply with Tbles 7, 8 nd 9 in the normlized or normlized rolled condition s well s fter normlizing by het tretment fter delivery For products supplied srolled for normlizing by the purchser the smples shll be normlized, if requested t the time of the order. The vlues obtined from the normlized smples shll comply with this document. The results shll be reported in the inspection document. NOTE The results of these tests do not represent the properties of the supplied products but indicte the properties which cn be chieved fter correct normlizing. 10

13 EN :2004 (E) For flt products the nominl thickness pplies. For long products of irregulr section the nominl thickness of tht prt from which the smples re tken pplies (see Anne A of EN :2004) Impct properties The verifiction of the impct energy vlue shll be crried out in ccordnce with EN The impct properties of qulity JR products re verified only when specified t the time of the order. See option For products of qulity J2 nd K2 with nominl thickness < 6 mm the ferritic grin size shll be 6, verified by the method s described in EN ISO 643, if specified t the time of the order. See option 21. When luminum is used s the grin refining element, the grin size requirement shll be deemed to be fulfilled if on ldle nlysis the luminum content is not less thn 0,020 totl luminum or lterntively, 0,015 cid soluble luminum. In this cse verifiction of the grin size is not required, but the luminum content shll be indicted in the inspection document Improved deformtion properties perpendiculr to the surfce If greed t the time of the order products of qulities J2 nd K2 shll comply with one of the requirements of EN See option Technologicl properties Weldbility Generl requirements for welding of the steels of the qulities JR, J0, J2 nd K2 shll be given in EN NOTE With incresing product thickness nd strength level cold crcking cn occur. Cold crcking is cused by the following fctors in combintion: the mount of diffusible hydrogen in the weld metl; brittle structure of the het ffected zone; significnt tensile stress concentrtions in the welded joint This document gives no informtion concerning the weldbility of the steel grdes S185, E295, E335 nd E360 becuse the chemicl composition is not specified Formbility NOTE Recommendtions regrding hot nd cold forming re lid down in ECSC IC 2. Although ECSC IC2 is specilly ment for fine grin steels, these recommendtions cn lso pply for the steel grdes of EN : Hot forming Only products ordered nd supplied in the normlized or normlized rolled condition shll comply with the requirements of Tbles 7, 8 nd 9 if hot forming is crried out fter delivery (see ). 11

14 EN :2004 (E) Cold formbility Generl Grdes nd qulities suitble for cold forming nd engineering steels suitble for cold drwing shll be designted by the pproprite steel nme (including symbol C or GC) or the pproprite steel number s indicted in Tbles 10 to 13 (see 4.2.2). NOTE Cold forming leds to reduction in the ductility. Furthermore it is necessry to drw the ttention to the risk of brittle frcture in connection with hotdip zinccoting Flngebility If specified t the time of the order plte, sheet, strip, wide flts nd flts (width < 150 mm) with nominl thickness 30 mm shll be suitble for flnging without crcking with the minimum recommended bend rdii given in Tble 12. The grdes nd qulities to which this pplies re given in Tble 10. See option Roll forming If specified t the time of the order plte, sheet nd strip with nominl thickness 8 mm shll be suitble for the production of sections by cold rolling (for emple ccording to EN 10162). The suitbility is pplicble for bend rdii given in Tble 13. The grdes nd qulities concerned re given in Tble 10. See option Drwing of brs If specified t the time of the order, brs shll be suitble for cold drwing. The grdes nd qulities to which this pplies re given in Tbles 10 nd 11. See option Suitbility for hotdip zinccoting Hotdip zinccoting requirements shll be greed between mnufcturer nd purchser. EN ISO 1461 nd EN ISO should be used to set these coting requirements. The definition of suitbility clsses bsed upon chemicl nlysis limittions s lid down in Tble 1 cn be used for guidnce purposes.

These increses pply for S5 nd S355 (see 7.2.5). See option 5. NOTE Product shpe, composition of the zinc bth, other hotdip tretment settings nd other fctors should be considered when greeing upon hotdip zinccoting requirements Mchinbility All steel grdes nd qulities re mchinble with common opertions. NOTE Due to the good ductility of qulities JR, J0, J2 nd K2 problems cn occur in the chip formtion nd in surfce finish qulity. Generlly higher S content improves mchinbility. A proper C tretment pplicble for long products gives better mchining properties (see footnote e of Tble 2 nd footnote c of Tble 3). 7.5 Surfce properties Strip The surfce condition should not impir n ppliction pproprite to the steel grde if dequte processing of the strip is pplied Pltes nd wide flts EN prts 1 nd 2 shll pply for the permissible surfce discontinuities nd for the repir of surfce defects by grinding nd/or welding.
