EN 10270-1:2011+A1:2017 (E) 4 European foreword This document (EN 10270-1:2011+A1:2017) has been prepared by Technical Committee ECISS/TC 106 “Wire rod and wires”, 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of an identical text or by endorsement, at the latest by November 2017, and conflicting national standards shall be withdrawn at the latest by November 2017. 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 includes Amendment 1 approved by CEN on 24 March 2017. This document supersedes !EN 10270-1:2011". The start and finish of text introduced or altered by amendment is indicated in the text by tags !". This European Standard for steel wire for mechanical springs is composed of the following parts: — Part 1: Patented cold drawn unalloyed spring steel wire; — Part 2: Oil hardened and tempered spring steel wire; — Part 3: Stainless spring steel wire. 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, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 10270-1:2011+A1:2017 (E) 6 3 Terms and definitions For the purposes of this document, the following !term and definition applies". 3.1 patented cold drawn wire wire drawn to size by cold deformation of a starting material that has been subjected to a thermal treatment of patenting (see EN 10052), giving structure suitable for subsequent rolling or drawing 4 Classification The grade of spring wire used depends on the stress level and the nature of the duty. Where springs are subjected to static stresses or infrequent dynamic loading a wire grade for static duty (S) shall be used. In the other cases with frequent or predominantly dynamic loading and where small coiling ratios or severe bending radius is required, a wire grade for dynamic duty (D) shall be used. Depending on the stress level, spring wire is manufactured in 3 tensile strength grades: !low", medium and high. Table 1 gives an overview of the different grades. Table 1 — Spring wire grades Tensile strength a Static Dynamic Low tensile strength SL — Medium tensile strength SM DM High tensile strength SH DH a

For specific applications another tensile strength may be agreed.

5 Information to be supplied by the purchaser The purchaser shall clearly state in his enquiry or order the product and following information: a) the desired quantity; b) the term spring steel wire or straightened and cut lengths; c) the number of this European standard: EN 10270-1; d) the steel grade (see Tables 1 and 2); e) the nominal wire diameter selected from Table 3 and for cut length the length and the length tolerance class (see Table 7); f) the coating indicated by its abbreviation and surface finish (see 6.3); g) the form of delivery and unit mass (see 6.2); h) the type of inspection document !(see 7.1)"; i) any particular agreement.

For individual sizes the carbon range is substantially more restricted. b For the manganese content, a different range from the one indicated in the table may be agreed at the time of ordering, with a maximum not exceeding 1,20 % and with a minimum range of 0,20 %.

" The addition of micro-alloying elements may be agreed between the manufacturer and the purchaser. NOTE Some diameter ranges require particular attention for residuals. Therefore no figures are mentioned for chromium, nickel, molybdenum, tin, etc., leaving room for special arrangements between Purchaser and Supplier, dependent on their mutual processing conditions. This is also the case for the aluminium content. 6.2 Form of delivery The wire shall be delivered in unit packages of a coil (singles, carriers or formers), spools, spoolless cores or as straight lengths. Unless otherwise agreed at the time of ordering, the form of delivery will be coils; straight lengths shall be supplied in bundles. SIST EN 10270-1:2012+A1:2017

Other coatings, considered as special, can be agreed between the purchaser and the supplier (see Annex A). If no specific surface finish is specified, the type of finish shall be at the manufacturer’s discretion. In addition the wire can be ordered with an oiled surface for all surface finishes. 6.4 Mechanical properties For the tensile strength (Rm) and reduction in area after fracture (Z) the wire grades shall satisfy the values listed in Table 3. !Reduction of area shall be measured only for wire diameter 0,80 mm < d."
