11、S 1554:1990 ii BSI 02-1999 Foreword This British Standard has been prepared under the direction of the Iron and Steel Standards Policy Committee. It is a revision of BS 1554:1981 which is withdrawn. In this revision the number of steels specified has been increased to align with current practice and
12、 to take account of the needs of the wire weaving industry. Dimensional tolerances appropriate to wire weaving have also been introduced. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct applicatio
13、n Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 12, an inside back cover and a back cover. This standard has been updated (see copyright date) and
14、 may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 24 08:16:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 1554:1990 BSI 02-19991 1 Scope This British Standard specifies stainless and h
15、eat-resisting steel round wire, supplied in coils, on spools or in straight lengths, suitable for general engineering purposes. It is applicable to wire sizes in the range from 0.03 mm diameter up to and including 13 mm diameter. This standard does not specify steel wires intended for springs, gas s
16、hielded welding, roping or cold heading. NOTE 1The information to be supplied by the purchaser in the enquiry and order is given in Appendix A. NOTE 2The titles of the publications referred to in this standard are listed on the inside back cover. 2 Manufacture and properties 2.1 Steelmaking process
17、The steel shall be made by an electric furnace process. 2.2 Chemical composition The chemical composition of the steel, based on cast analysis, shall be as given in Table 1, Table 2, Table 3 and Table 4, as appropriate. Any subsequent analytical checks of composition of the wire shall take into cons
18、ideration analytical reproducibility and the heterogeneity that is normal to the steel (see Appendix B). 2.3 Condition of finished wire 2.3.1 The wire shall be free from defects to a degree that would be harmful in the further processing or performance of the wire. NOTEThe end use of the wire, there
19、fore, should be the subject of discussion between the purchaser and manufacturer at the time of the enquiry and order (see item d) of Appendix A). 2.3.2 The wire shall be supplied either in the annealed (softened) or cold drawn condition. For austenitic stainless steel wire required in the softened
20、condition, the wire shall be heat treated in the temperature range 1 000 C to 1 120 C. NOTE 1The condition in which the wire is to be supplied should be agreed between the purchaser and manufacturer at the time of the enquiry and order (see item e) of Appendix A). NOTE 2Wire can be supplied with a g
21、round surface in either coils or straight cut lengths. It may be supplied with other surface finishes, e.g. wet drawn reeled, mechanically polished, drawn, to facilitate further fabrication processes. These should be subject to agreement between the purchaser and manufacturer at the time of the enqu
22、iry and order (see item f) of Appendix A). 2.4 Tensile strength The tensile strength of wire in the annealed condition shall be as given in Table 5. NOTE 1For wire less than 0.10 mm in diameter, the maximum tensile strength should be agreed between the purchaser and manufacturer at the time of the e
23、nquiry and order (see item g) of Appendix A). NOTE 2The tensile strength range for wire in the cold drawn condition should be agreed between the purchaser and manufacturer at the time of the enquiry and order (see item h) of Appendix A). The agreed range should be no greater than 200 N/mm2 (between
24、the minimum and maximum figures). 3 Method of supply The wire shall be supplied in coil form, wound on spools or formers, or as straight cut lengths, in bundles appropriate for the diameter of wire. Wire in coils or on a spool shall be supplied in single continuous lengths without knots or tie-ins (
25、see also item i) of Appendix A). NOTE 1The acceptability of welds in coils or spools should be agreed between the purchaser and manufacturer at the time of the enquiry and order (see item i) of Appendix A). NOTE 2The size of bundles for straight cut lengths should be agreed between purchaser and man
26、ufacturer at the time of the enquiry and order (see item j) of Appendix A). 4 Selection of test pieces 4.1 Test unit For the purpose of selection of test pieces, a test unit shall consist of all the wire from one cast, presented for inspection, in one form of supply, i.e. coils, spools or bundles, m
27、anufactured by the process to one finished condition. 4.2 Rate of sampling Test pieces shall be selected from a minimum of 10 % of the coils, spools or bundles in each test unit. Test pieces shall be taken from one end of each selected coil or spool. From each selected bundle a minimum of one length
28、 shall be taken at random. NOTEBy arrangement between purchaser and manufacturer a sampling plan based on BS 6001 may be used (see item k) of Appendix A). 4.3 Intercrystalline corrosion test For the intercrystalline corrosion test, one test piece shall be taken from each test unit. 5 Methods of test
29、ing 5.1 Diameter The diameter of the wire shall be the mean of two measurements of diameter at right angles at the same cross section of the wire. NOTEThe wire should be straightened prior to measurement. 5.2 Tensile tests Tensile tests shall be carried out in accordance with BS 4545. The tensile st
30、rength shall be calculated on the actual diameter of the wire as measured in accordance with 5.1. 5.3 Intercrystalline corrosion test When this test is specified by the purchaser it shall be carried out in accordance with BS 5903 (see item l) of Appendix A).

32、iven in Table 6 and as measured in accordance with 5.1. The ovality shall be defined as the difference between the maximum and minimum dimensions of the wire at the same cross section. Wire for weaving and special applications shall be supplied within tolerances on diameter and ovality as given in T
33、able 7 and as measured in accordance with 5.1. NOTETolerances on diameter and ovality for ground wire should be agreed between purchaser and manufacturer at time of the enquiry and order (see item m) of Appendix A). 7 Retests If any test piece fails any of the tests specified in clause 5 the manufac
34、turer may, at his discretion, retain or not retain in the test unit the product sample from which the unsatisfactory test results have been obtained. a) If the product sample is withdrawn from the test unit, the manufacturer shall ensure that the inspection representative designates within the same
35、test unit, two other product samples of his choice. Two more tests of the same type shall then be carried out on test pieces from these two product samples, under the same conditions as for the first tests; both new tests shall give satisfactory results. b) If the product sample is retained in the t
36、est unit, the procedure is as indicated in item a) but one of the new test pieces shall be taken from the product retained in the test unit; both new tests shall give satisfactory results. NOTEThe manufacturer has the right to carry out sorting or reprocessing, e.g. heat treatment, machining, rollin
37、g, drawing, of non-conforming products, either before or after the retests, and to submit these products as a new test unit in accordance with clause 4. 8 Packaging and marking Wire in coils, on spools or bundles of lengths shall be securely tied and each coil, spool or bundle shall be identified by
38、 a durable label on which shall be shown the following minimum information: a) the suppliers name; b) the steel designation; c) the number of this British Standard, i.e. BS 15541); d) the nominal wire diameter or size; e) the cast number; f) the condition, i.e. annealed, cold drawn; g) the range of
39、tensile strength and/or the condition of the wire as ordered, if appropriate. NOTEAny other packing requirements should be agreed between the purchaser and manufacturer at the time of the enquiry and order (see item n) of Appendix A).

40、ing BS 1554 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim.
41、Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.
