31、Terms and definitions For the purposes of this document, the terms and definitions given in EN 10079 apply. 4 Classification and designation 4.1 This European Standard specifies the grades listed in Table 1. In the case of steel grade DC01, the deoxidation method shall be left to the manufacturers d
32、iscretion. Steel grades DC03, DC04, DC05, DC06 and DC07 shall be supplied fully killed. 4.2 Products manufactured from these steels may be ordered and supplied in different delivery conditions (see Table 1) and with different surface characteristics (see 6.4 and Table 2). 4.3 For the purposes of the
33、 specifications of this European Standard, the selection of steel grade, delivery condition and surface characteristics are of the responsibility of the purchaser. NOTE 1 In case of narrow widths, strip complying with this European Standard can also be wound in layers and supplied in the form of a b
34、obbin wound coil. NOTE 2 After uncoiling and shearing, strip can be supplied in cut lengths. 5 Designation The symbol designation of the steel grades in this European Standard is in accordance with EN 10027-1 and the numerical designation is allocated in accordance with EN 10027-2. The standard desi
35、gnation consists of the words narrow strip or cut lengths, followed in order by: a) reference to this European Standard, EN 10139; b) the symbol DC, followed by the grade designation (01, 03, 04, 05, 06 and 07); c) the symbol for delivery condition (see Table 1); d) the symbol for surface appearance
36、 (MA, MB or MC, see Table 2); e) the symbol for surface finish where appropriate (RN, RL, RM or RR, see 6.4.3 and Table 2). EXAMPLE 1 Designation of cold rolled narrow strip, 1,50 mm thick, having a normal tolerance on the nominal thickness, a width of 200 mm, having a normal tolerance on the nomina
37、l width, slit edges (GK) and made from DIN EN 10139:2016-06 EN 10139:2016 (E) 6 steel grade DC04, in a lightly skin-passed condition (LC) with a smooth and uniform surface appearance (MB) and a “matt” surface finish (RM): Narrow strip EN 10140:2006 1,50 200 GK Steel EN 10139 DC04 + LC MB RM EXAMPLE
38、2 Designation of cold rolled narrow strip, 2,00 mm thick, having a normal tolerance on the nominal thickness, a width of 450 mm, having a normal tolerance on the nominal width, slit edges (GK) and made from steel grade DC03, in the annealed condition (A), with a bright, metallically clean surface ap
39、pearance (MA) and a smooth surface finish (RL): Narrow strip EN 10140:2006 2,00 450 GK Steel EN 10139 DC03 + A MA RL 6 Properties 6.1 Steel making process and chemical composition 6.1.1 The steel making process shall be left to the discretion of the manufacturer. 6.1.2 The chemical composition based
40、 on ladle analysis shall be as given in Table 1. 6.2 Choice of properties The products covered by this European Standard shall comply with the specifications given in Table 1. If agreed separately, they may be supplied with a special suitability for making a particular part; in this case, a maximum
41、percentage of processing scrap may be fixed by common agreement and acceptance tests on the basis of the mechanical properties shall not apply. 6.3 Mechanical and technological properties 6.3.1 The mechanical and technological properties of the products are given in Table 1. These properties are gua
42、ranteed for the periods specified in Table 1 with effect from the date that the products are made available for delivery. The purchaser shall be informed of this date when the products are to be made available, with a warning appropriate to the guarantee of mechanical properties. Storage of grade DC
43、01 products for more than 3 months may cause a change in the mechanical properties likely to give rise to a reduction in the suitability for forming and drawing. 6.3.2 The usual test for checking the mechanical properties given in Table 1 is the tensile test. However, if agreed at the time of orderi
44、ng, hardness values may be specified instead of tensile test properties, but not both. 6.3.3 The tensile test values shall apply to longitudinal test pieces. 6.4 Surface characteristics 6.4.1 General Surface characteristics concern surface appearance and surface finish. These shall be specified by t
45、he purchaser at the time of ordering. Unless otherwise specified at the time of ordering, the products shall be supplied with a surface appearance MA and a smooth surface finish RL (Ra 0,6 m). DIN EN 10139:2016-06 EN 10139:2016 (E) 76.4.2 Surface appearance 6.4.2.1 Cold rolled flat products covered
46、by this European Standard may be supplied with surface appearances MA, MB or MC as described in Table 2. The required surface appearance shall be stated in the designation (see Clause 5). 6.4.2.2 The characteristics indicated in Table 2 apply to the surface actually inspected, which is generally the
47、 outside surface of coils and the top surface of lengths. The appearance of the uninspected surface shall correspond at least to surface appearance MA. These characteristics shall not apply to the first two inner and outer laps of coil or to lengths cut from them. 6.4.3 Surface finish 6.4.3.1 The su
48、rface finish may be rough, matt, smooth or mirror finish, as given in Table 2. Products with surface appearances MA and MB are generally supplied with a smooth surface finish (RL). If rough (RR) or matt (RM) finishes are required, the corresponding symbol shall be given in the designation (see Claus
49、e 5). The surface appearance MC shall only be supplied with a “mirror” finish (RN). 6.4.3.2 The different surfaces finishes are characterized by the following reference values of mean roughness Ra: RR: rough: Ra 1,5 m; RM: matt: 0,6 m Ra 1,8 m; RL: smooth: Ra 0,6 m; RN: mirror finish: Ra 0,2 m. 6.5 Stretcher strain marks The tendency towards the formation of fractures or stretcher strain marks during forming may be eliminated for a time by light skin-passing (LC) after annealing.
