22、 DiscussionThe straightening operation may alter the mechanical properties of the wire, especially the tensile strength. The straighteningoperation may also induce changes in the diameter of the wire. The extent of the changes in the properties of the wire after coldstraightening depends upon the ki
23、nd of wire and also on the normal variations in the adjustments of the straightening equipment.It is therefore not possible to forecast the properties of straightened and cut wire and each kind of wire needs individualconsideration. In most cases, the end use of straightened and cut wire is not seri
24、ously influenced by these changes.3.1.3 wire rodsrods that are hot rolled from billets to an approximate round cross section into coils of one continuous length.Rods are not comparable to hot-rolled bars in accuracy of cross section or surface finish and as a semifinished product are intendedprimari

Manufactur
34、e5.1 The steel shall be made by the electric-furnace, basic-oxygen or other similar any commercially accepted steel makingprocess. The steel may be either ingot cast or strand cast.6. Chemical Composition6.1 The chemical composition for steel under this specification shall conform to the requirement
35、s set forth in the purchase order.Chemical compositions are specified by ranges or limits for carbon and other elements. The grades commonly specified for carbonand alloy steel wire rods and coarse round wire are designated in Guide A1040.6.1.1 For wire rods intended for direct-drawn wire, it is com
36、mon practice to specify a range of tensile strength. If chemistryranges are also specified, due consideration should be taken to ensure that the producer can achieve the required strengths withinthe allowable carbon range. The Mn, P, and S limits for carbon steel wire rods are normally specified acc
37、ording to Guide A1040.6.2 Boron Additions to Control Strain Ageing BehaviorIntentional additions of boron to low carbon steels for the purpose ofcontrolling strain ageing behavior during wire drawing is permissible only with the agreement of the purchaser. In such cases, theboron content shall be re
38、ported in either a material test report or certification.6.2.1 For steels that do not have intentional boron additions for hardenability or for control of strain ageing behavior, the boroncontent will not normally exceed 0.0008 %.6.3 Cast or Heat Analysis (Formerly Ladle Analysis)An analysis of each
39、 cast or heat shall be made by the producer todetermine the percentage of the elements specified. The analysis shall be made from a test sample, preferably taken during thepouring of the cast or heat. The chemical composition thus determined shall be reported, if required, to the purchaser, or hisre
40、presentative. Reporting of significant figures and rounding shall be in accordance with Test Methods, Practices, and TerminologyA751.6.4 Product Analysis (Formerly Check Analysis)A product analysis may be made by the purchaser. The analysis is not usedfor a duplicate analysis to confirm a previous r
41、esult. The purpose of the product analysis is to verify that the chemical compositionis within specified limits for each element, including applicable permissible variations in product analysis. The results of analysestaken from different pieces of a heat may differ within permissible limits from ea
42、ch other and from the heat or cast analysis. Table3 shows the permissible variations for product analysis of carbon steel. Table 4 shows the permissible variations for productanalysis of alloy steel. The results of the product analysis obtained, except lead, shall not vary both above and below thepe
43、rmissible limits.6.4.1 Rimmed or capped steels are characterized by a lack of uniformity in their chemical composition, especially for theelements carbon, phosphorus, and sulfur, and for this reason product analysis is not technologically appropriate for these elementsunless misapplication is clearl
44、y indicated.6.4.2 Because of the degree to which phosphorus and sulfur segregate, product analysis for these elements is not technologicallyappropriate for rephosphorized or resulfurized steels, or both, unless misapplication is clearly indicated.6.4.3 The location at which chips for product analysi
45、s are obtained from the sample is important because of segregation. Forrods and wire, chips are taken by milling or machining the full cross section of the sample.A510/A510M 1346.4.3.1 Steel subjected to certain thermal treatment operations by the purchaser may not give chemical analysis results tha
46、tproperly represent its original composition. Therefore, purchasers should analyze chips taken from the steel in the condition inwhich it is received from the producer.6.4.3.2 When samples are returned to the producer for product analysis, the samples should consist of pieces of the full crosssectio
47、n.6.4.4 For referee purposes, Test Methods E30 shall be used.7. Metallurgical Structure7.1 Grain size, when specified, shall be determined in accordance with the requirements of Test Methods E112.7.2 Wire rods of the steel grades listed in Table 3, when supplied in the “as-rolled condition, shall no
48、t contain injuriousmicroconstituents such as untempered martensite.8. Mechanical Requirements8.1 The properties enumerated in individual specifications shall be determined in accordance with Test Methods and DefinitionsA370.8.2 Because of the great variety in the kinds of wire and the extensive dive
49、rsity of end uses, a number of formal mechanicaltest procedures have been developed. These tests are used as control tests by producers during the intermediate stages of wireprocessing, as well as for final testing of the finished product, and apply particularly to specification wire and wires for specifiedend uses. A number of these tests are further described in Supplement IV, Round Wire Products, of Test Methods and DefinitionsA370.8.3 Since the general utility of rods and wire requires
