European foreword This document (EN 10139:2016) has been prepared by Technical Committee ECISS/TC 109 “Coated and uncoated flat products to be used for cold forming”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by August 2016, and conflicting national standards shall be withdrawn at the latest by August 2016. 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. This document supersedes EN 10139:1997. 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.

These products are suitable for cold forming. They are also suitable for surface coating. On the other hand, they are not suitable for hardening treatment followed by tempering. 1.2 This European Standard does not cover cold rolled flat products for which a separate standard already exists, particularly the following products: — cold rolled non-oriented electrical steel sheet and strip delivered in the fully processed state (EN 10106); — grain-oriented electrical steel sheet and strip delivered in the fully processed state (EN 10107); — cold rolled electrical non-alloy and alloy steel sheet and strip delivered in the semi-processed state (EN 10341); — cold rolled narrow steel strip for heat treatment (EN 10132-1 to

«4); — cold rolled steel flat products with higher yield strength for cold forming (EN 10268); — cold rolled low carbon steel flat products for cold forming (EN 10130); — cold reduced blackplate in coil form for the production of tinplate or electrolytic chromium/chromium oxide coated steel (EN 10205); — cold rolled low carbon steel flat products for vitreous enamelling (EN 10209). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

In the case of steel grade DC01, the deoxidation method shall be left to the manufacturer’s discretion. 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 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 bobbin 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 designation 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 (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 nominal width, slit edges (GK) and made from SIST EN 10139:2016

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 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 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 guaranteed 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 DC01 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 ordering, hardness values may be specified instead of tensile test properties, but not both. 6.3.3 The tensile test values shall apply to longitu
