BS EN 10209:2013EN 10209:2013 (E) 4 1 Scope This European Standard applies to cold rolled non-coated low carbon steel flat products in rolled widths equal to or over 600 mm and in thi
18、cknesses equal to or less than 3 mm, delivered in sheet, wide strip, slit wide strip or cut lengths obtained from slit wide strip or sheet. It does not apply to cold rolled narrow strip (rolling width 1,6 m 5.9 Stretcher strain marks All the products are generally subjected to a light skin-pass afte
19、r annealing at the manufacturers works to avoid the formation of stretcher strain marks during subsequent forming. The tendency to form such marks may reappear a certain time after the skin-pass. It is therefore in the purchasers interest to form the products as soon as possible. Quality DC06EK and
20、DC06ED products do not exhibit stretcher strain marks after deformation. For the other qualities the absence of stretcher strain marks may be guaranteed for six months after the products are made available. 5.10 Weldability The material is specified as suitable for normal welding procedures as long
21、as the products are degreased beforehand. The welding procedure shall be specified at the time of ordering (see 10 h). 5.11 Tolerances on dimensions and shape Tolerances on dimensions and shape are given in EN 10131. BS EN 10209:2013EN 10209:2013 (E) 8 6 Tests 6.1 General 6.1.1 The purchaser shall s
22、pecify at the time of ordering his requirements for: type of inspection and testing: specific or non-specific, see EN 10021; type of inspection document, see EN 10204. 6.1.2 Specific inspection and testing shall be carried out in accordance with 6.2, 6.3, 6.4, 6.5 and 6.6. 6.1.3 Specific inspection
23、and testing may not be specified either for the product analysis or the surface finish. 6.2 Inspection units The inspection unit is 30 t or a fraction of 30 t products of the same grade and nominal thickness. When a wide coil exceeds 30 t, it constitutes a single inspection unit, as do its products.
24、 6.3 Number of tests For each inspection unit a tensile test shall be carried out, and if required, a determination of r and of the suitability for enamelling shall be performed (see Table 2 and Annex A, Annex B and Annex C). 6.4 Sampling The requirements of EN ISO 377 and EN 10021 are supplemented
25、by the following specific requirements. For sheet and cut lengths the selection of products to be tested and the position of the samples in the products is left to the discretion of the inspection representative. In the case of wide strip and slit wide strip, the sample should preferably be taken fr
26、om the outer end. If the width of the product permits, the test pieces for the tensile test shall be taken perpendicular to the direction of rolling at a distance of at least 50 mm from the edge of the product. 6.5 Test methods 6.5.1 The products shall be tested in the as-delivered condition. The te
27、sts shall be carried out at ambient temperature. 6.5.2 The tensile test shall be carried out as specified in EN ISO 6892-1 using type 2 test pieces (initial gauge length Lo= 80 mm, width b = 20 mm). 6.5.3 Surface roughness shall be measured in accordance with EN 10049. 6.5.4 The determination of the
28、 plastic strain ratio r shall be carried out in accordance with ISO 10113. 6.5.5 The tests for suitability for enamelling (see 5.4.3) shall be carried out in accordance with Annex A for the fish scaling resistance test; Annex B for the mass loss due to pickling test; Annex C for the adherence test.
29、BS EN 10209:2013EN 10209:2013 (E) 9 6.5.6 For the determination of the chemical composition the corresponding European Standards shall apply in cases of dispute. 6.6 Retests The requirements of EN 10021 shall apply. For coils, in the event of the test results giving rise to dispute, the samples for
30、retests shall be taken at intervals of at least one lap but also at a maximum distance of 20 m from the appropriate end. 6.7 Inspection documents If agreed at the time of ordering, an inspection document chosen from those given in EN 10204 shall be supplied (see also 6.1.1). 7 Identification All mat
31、erials shall be identified with at least the following information: the conventional designation as described in Clause 4; the coil or bundle number; the suppliers mark. Typically, the identification is applied by either a label or using an easily removable non-corrosive ink on the inspected surface
32、. Other identification requirements shall be agreed at the time of ordering. 8 Packaging The packaging requirements shall be agreed at the time of ordering. 9 Disputes With regard to any claims and actions, EN 10021 shall apply. 10 Information to be supplied by the purchaser at the time of ordering
33、To permit the manufacturer to supply products conforming to this standard, the following information should be given in the order: a) the full designation as given in Clause 4; b) nominal dimensions and quantities; c) if the products are to be supplied non skin-passed, d) if the products are to be d
34、elivered with mill edges or sheared edges; e) limits on mass and sizes of coils and individual bundles; f) intended application for the products; g) enamelling process used (see Annex D); BS EN 10209:2013EN 10209:2013 (E) 10 h) if the products are to be welded, indication of the method to be used; i
35、) if the products are to be supplied as suitable for making a specific part; j) if inspection documents are requested and type; k) if an external inspection is to be carried out at the manufacturers works; l) if oiling is not required; m) detailed description of all other special requirements; n) an
36、y special requirements for packaging and marking; o) the position of the surface of better surface finish quality.

For thicknesses less than or equal to 0,5 mm, the value is increased by 40 MPa. cFor design purposes, the lower limit o
41、f Refor qualities DCO1EK, DC04EK, DC05EK, DC03ED and DC04ED may be assumed to be 140 MPa and for qualities DC06EK and DC06ED as 120 MPa. dWhen the thickness is less than or equal to 0,7 mm, and greater than 0,5 mm, the minimum elongation value after fracture is reduced by 2 units. For thicknesses eq
42、ual to or less than 0,5 mm, the minimum value is reduced by 4 units. eThe value of r average only applies to products of thicknesses equal to or greater than 0,5 mm. When the thickness is over 2,0 mm, the value of r average is reduced by 0,2 units. fSubject to agreement at the time of ordering, othe
43、r deoxidation methods may be used. If so, the periods for validity of the mechanical properties and the absence of stretcher strain marks shall be agreed at the time of ordering. BS EN 10209:2013EN 10209:2013 (E) 12 gIf the thickness is greater than or equal to 1,5 mm, the maximum value for the yiel
44、d stress may reach 225 MPa. hTitanium may be replaced by niobium if agreed upon at the time of ordering. Carbon and nitrogen shall be completely bound. iSubject to agreement at the time of ordering, other steels may be supplied which have the same mechanical properties. If so, the chemical compositi
45、on of these steels shall be agreed at the time of ordering. jThe decarburisation of qualities DC03ED and DC04ED can take place in the solid or the liquid phase. The carbon content, determined by product analysis after decarburisation shall be 0,004 % maximum. If agreed at the time of ordering, quali
46、ties DC03ED and DC04ED may contain for example titanium, niobium or boron. kAt the request of the purchaser, the DC04EK and DC05EK qualities may be supplied with Re 210 MPa and A80 38 % in the 0,7 mm to 1,5 mm thicknesses. It is therefore for the manufacturer to select the surface roughness within t
47、he range of normal roughness options. l The mechanical property values refer to the perpendicular testing direction.
