7、a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represent

8、ed on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop

9、this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC

10、 Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the

11、development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

13、l, Subcommittee SC 4, Heat treatable and alloy steels. This second edition cancels and replaces the first edition (ISO 16143-3:2005), which has been technically revised. ISO 16143 consists of the following parts, under the general title Stainless steels for general purposes: Part 1: Corrosion-resist

14、ant flat products Part 2: Corrosion-resistant semi-finished products, bars, rods and sections Part 3: Wireiv ISO 2014 All rights reserved INTERNATIONAL ST ANDARD ISO 16143-3:2014(E) Stainless steels for general purposes Part 3: Wire 1 Scope This part of ISO 16143 specifies requirements for stainless

15、 steel wire for common use for which no product standard exists. It includes round, flat, and shaped wire (such as square, hexagonal, or rectangular wire), made of the most commonly used types of stainless steels for general corrosion resistance and high-temperature service. The wire can be supplied

16、 in coils or in straightened and cut lengths. NOTE Steel wire made of corrosion-resistant stainless steel is manufactured from steels mentioned in ISO 16143-2, and steel wire intended for high-temperature purposes is manufactured from steels mentioned in ISO 4955. In addition to this part of ISO 161

17、43, the general technical delivery requirements of ISO 404 are applicable. Excluded from this part of ISO 16143 are wire for cold heading, welding wire, and any wire for which a specific product standard exists. 2 Normative references The following documents, in whole or in part, are normatively ref

32、on of the manufacturer. 6.2 Treatment conditions The wire shall be specified in one of the following conditions, depending on the structure: Condition +A: The wire is annealed as the final heat treatment. Note that this material might be slightly deformed by straightening, cold work, size control, o

33、r finish. This will result in a slight increase of the tensile strength. Condition +AT: The wire is solution annealed as the final heat treatment. Note that this material might be slightly deformed by straightening, cold work, size control, or finish. This will result in a slight increase of the ten

34、sile strength. Condition +C: The wire is hard drawn as the last operation, in order to achieve higher strength. 6.3 Surfac e finish If not specified otherwise, the surface finish of the wire is one of the following, depending on previous processing steps. 6.3.1 Cold drawn This is the natural finish

35、resulting from the drawing to final size, generally with cold-drawing lubricant left on. The finish will be duller for dry-drawn wire or shinier for wire that is wet drawn. Fine sizes are commonly wet drawn, whereas coarser sizes are commonly dry drawn. Special bright finishes, lubricant removal, et

36、c. required for special end-use shall be negotiated with the manufacturer. ISO 2014 All rights reserved 3 ISO 16143-3:2014(E) 6.3.2 Annealed This is a dull matt appearance, necessarily associated with the dead soft condition of annealed wire when no final drawing is permitted. With an additional sur

37、face treatment, a bright appearance can be realized. 6.3.3 P olished finish This is a smooth and uniform bright finish of cold-processed (+C) material obtained by mechanical smoothing, burnishing, abrading, or grinding. 7 Requirements 7.1 Manufacturing process The steelmaking process for products ac

38、cording to this part of ISO 16143 shall be in accordance with ISO 4955 and ISO 16143-2. The wire processing, insofar as it is not specified in this part of ISO 16143 or agreed between the parties, shall be at the discretion of the wire drawer. 7.2 Delivery condition The product shall be supplied as

39、described in Clause 6 and agreed in the order. 7.3 Chemical analysis 7.3.1 Cast analysis The chemical composition requirements given in Table 1 apply with respect to the chemical composition of the cast analysis. 7.3.2 Product analysis The product analysis can deviate from the limiting values for th

40、e cast analysis given in Table 1 by the values listed in Table 2. 7.4 Mechanical properties 7.4.1 Mechanical properties for annealed wire The tensile strength and elongation shall satisfy the requirements of Table 3. It specifies the mechanical properties at room temperature in the annealed conditio

41、n. For austenitic, austenitic-ferritic, and precipitiation-hardening steels, the wire is in the condition +AT; for ferritic and martensitic steels, this is in the condition +A. 7.4.2 Mechanical properties of hard-drawn wire This wire is in condition +C The tensile strength will depend on the degree

42、of work hardening, the specific type of steel, and the processing of the material. The tensile strength is specified by a minimum and maximum. Not all the tensile strength levels listed in Table 4 can be achieved for all steel grades. Therefore, the required tensile-strength level shall be agreed be

43、tween the manufacturer and the purchaser at the time of ordering. Table 4 gives an overview of the standardized tensile-strength levels and the corresponding minimum and maximum.4 ISO 2014 All rights reserved ISO 16143-3:2014(E) 7.5 Tolerances on dimensions For round wire, the purchaser shall specif

44、y normal tolerance (N) or restricted tolerance (R), as defined in Table 5. For non-round wire, tolerances shall be agreed upon at the time of ordering. The out-of-roundness is the difference between the largest and the smallest diameter in the same cross section of the wire. The cross section shall

45、be perpendicular to the longitudinal wire axis. The out-of- roundness shall not exceed half the total diameter tolerance specified for coils. 8 Inspection, testing, and conformance of products 8.1 General The manufacturer shall carry out appropriate process control, inspection, and testing to ensure

46、 that the delivery complies with the requirements of the order. This includes the following: a suitable frequency of verification of the dimensions of the products; an adequate intensity of visual examination of the surface quality of the products; an appropriate frequency and type of test to ensure

47、 that the correct grade of steel is delivered. The nature and frequency of these verifications, examinations, and tests are determined by the manufacturer, based on the degree of consistency that has been determined by the evidence of his quality system. In view of this, verifications by specific te

48、sts for these requirements are not necessary, unless otherwise agreed. 8.2 Inspection and testing procedures and types of inspection documents 8.2.1 Products complying with this part of ISO 16143 shall be ordered and delivered with one of the inspection documents as specified in ISO 10474. The type

49、of document shall be agreed upon at the time of enquiry and order. If the order does not contain any specification of this type, a test report 2.2 shall be issued. 8.2.2 If, in accordance with the agreements made at the time of ordering, a test report is to be provided, this shall cover a) the statement that the material complies with the requirements of the order and b) the results of the cast analysis for all elements specified for the type of steel supplied. 8.2.3 If
