21、mingDIN EN 10209:2013-09EN 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 thicknesses equal to or less than 3 mm, delivered in sheet, wide strip, slit wide strip or cut lengths obtained
22、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 after annealing at the manufacturers works to avoid the formation of stretcher strain marks during subsequent for
23、ming. 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 DC06ED products do not exhibit stretcher strain marks after deformation. For the other qualities the absence
24、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 as the products are degreased beforehand. The welding procedure shall be specified at the time of ordering (s
25、ee 10 h). 5.11 Tolerances on dimensions and shape Tolerances on dimensions and shape are given in EN 10131. DIN EN 10209:2013-09EN 10209:2013 (E) 8 6 Tests 6.1 General 6.1.1 The purchaser shall specify at the time of ordering his requirements for: type of inspection and testing: specific or non-spec
26、ific, 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 and testing may not be specified either for the product analysis or the surface finish. 6.2 Inspection un
27、its 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. 6.3 Number of tests For each inspection unit a tensile test shall be carried out, and if required, a det
28、ermination 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 by the following specific requirements. For sheet and cut lengths the selection of products to be tested
29、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 from the outer end. If the width of the product permits, the test pieces for the tensile test shall be take
30、n 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 tests shall be carried out at ambient temperature. 6.5.2 The tensile test shall be carried out as specified
31、 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 plastic strain ratio r shall be carried out in accordance with ISO 10113. 6.5.5 The tests for suitabilit
32、y 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. DIN EN 10209:2013-09EN 10209:2013 (E) 9 6.5.6 For the determination of the chemical composition the corre
33、sponding 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 retests shall be taken at intervals of at least one lap but also at a maximum distance of 20 m from t
34、he 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 materials shall be identified with at least the following information: the conventional designation as d
35、escribed 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. Other identification requirements shall be agreed at the time of ordering. 8 Packaging The packagin
36、g 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 To permit the manufacturer to supply products conforming to this standard, the following information
37、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 delivered with mill edges or sheared edges; e) limits on mass and sizes of coils and individual bundle

39、uments 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) any special requirements for packaging and marking; o) the position of the surface of better surfac

When the thickness is less than or equa
44、l to 0,7 mm and greater than 0,5 mm, the value for yield stress is increased by 20 MPa. For thicknesses less than or equal to 0,5 mm, the value is increased by 40 MPa. cFor design purposes, the lower limit of Refor qualities DCO1EK, DC04EK, DC05EK, DC03ED and DC04ED may be assumed to be 140 MPa and
45、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 equal to or less than 0,5 mm, the minimum value is reduced by 4 units. eThe value of r average
46、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, other deoxidation methods may be used. If so, the periods for validity of the mechanical properti
47、es and the absence of stretcher strain marks shall be agreed at the time of ordering.

If so, the chemical composition 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, qualities DC03ED and
