16、-fications itemized in 1.1, is any round or shaped cold-reducedproduct, in coils only, produced by cold-finishing coiled wirerod.3.1.3 wire rodssemifinished product intended primarilyfor the manufacture of wire. They are hot rolled generally to anapproximate round cross section in continuous length

17、coils.4. Materials and Manufacture4.1 The material may be furnished in one of the conditionsdetailed in the applicable material specification, that is, an-nealed, bright annealed, cold worked, or as otherwise specifiedon the purchase order.4.2 A variety of finishes, coatings, and lubricants are avai

18、l-able. The particular type used is dependent upon the specificend use. Unless otherwise specified, the finish, coating, andlubricant will be furnished as required by the individualmaterial specification or purchase order.5. Chemical Composition5.1 Heat or Cast AnalysisThe chemical analysis of eachh

19、eat shall be determined in accordance with the applicablematerial specification and Test Methods, Practices, and Termi-nology A 751.5.1.1 The analysis of each heat shall be made from a testsample taken during the pouring of the melt, or from thein-process product later in the manufacturing flow.5.1.

20、2 The heat analysis shall conform to the chemicalrequirements for each of the specified elements for the gradeordered, as listed in the applicable product specification.5.1.3 All commercial metals contain small amounts ofelements other than those which are specified. It is neitherpractical nor neces

21、sary to specify limits for unspecified ele-ments, whether intentionally added unspecified elements, re-sidual elements, or trace elements, that can be present. Theproducer is permitted to analyze for unspecified elements andis permitted to report such analyses. The presence of anunspecified element

22、and the reporting of an analysis for thatelement shall not be a basis for rejection unless the presence ofthat element causes the loss of a property typically expected forthat metal for the type and quality ordered.5.1.4 The purchaser is permitted to require in the purchaseorder a maximum limit for

23、an individual element not specifiedin the product specification. Such a requirement for an elementnot listed in the product specification, when acknowledged inthe order acceptance, shall be treated as a specified element,with determination of chemical analysis and reporting of thatanalysis.5.1.5 The

24、 purchaser is permitted to make the requirementsfor any element more stringent, that is, require higher mini-mums for elements having minimum requirements or rangeswith minimum requirements, or requiring lower maximums forelements having specified maximums, or ranges with maxi-mums. The purchaser is

25、 not permitted to make chemicalrequirements less stringent.5.1.6 Analysis limits shall be established for specificelements rather than groups of elements, including but notlimited to “all others,” “rare earths,” and “balance,” unless allelements in such a group are similar in technical effect and ar

26、eassociated in typical methods of chemical analysis.5.2 Product AnalysisWhen required, a product analysisshall be determined in accordance with Test Methods, Prac-tices, and Terminology A 751. The chemical composition thusdetermined shall conform to the tolerances shown in Table 1.5.3 The steel shal

27、l not contain an unspecified element forthe ordered grade to the extent that the steel conforms to therequirements of another grade in the referencing productspecification, and any of the product specifications within thescope of this general specification, for which that element hasa specified mini

28、mum.6. Permissible Variations in Dimensions6.1 Unless otherwise specified in the purchase order, theproduct shall conform to the permissible variations in dimen-sions as specified in Tables 2-5 of this specification.7. Workmanship, Finish, and Appearance7.1 The material shall be of uniform quality c

29、onsistent withgood manufacturing and inspection practices. Imperfectionsthat may be present shall be of such a nature or degree, for thetype and quality ordered, that they will not adversely affect theforming, machining, or fabrication of finished parts.8. Lot Size8.1 A lot for product analysis shal

30、l consist of all wire madefrom the same heat.8.2 For other tests required by the product specification, alot shall consist of all product of the same size, same heat, andproduced under the same processing conditions. All austenitic,ferritic, and free-machining stainless steels, as well as marten-sit

31、ic grades when annealed to Condition A and precipitation orage hardening grades when solution treated, may be heattreated in more than one charge in the same furnace or inseveral furnaces, utilizing controlled processing and equipment(see appendix). However, when heat treating martensitic stain-less

32、 steels to Condition T or H and when age hardening theprecipitation hardening stainless steels, a lot shall consist of thesame size, same heat, and the same heat treat charge in abatch-type furnace or under the same conditions in a continu-ous furnace.9. Number of Tests and Retests9.1 Unless otherwi

33、se specified in the product specification,one sample per heat shall be selected for chemical analysis andone mechanical test sample shall be selected from each lot ofwire. All tests shall conform to the chemical and mechanicalrequirements of the material specification.9.2 One intergranular corrosion

34、 test, when required, and onegrain size test, when required, shall be made from each lot. Itis often convenient to obtain test material from the specimenselected for mechanical testing.9.3 If any test specimen shows imperfections that may affectthe test results, it may be discarded and another speci

35、mensubstituted.9.4 If the results of any test lot are not in conformance withthe requirements of this specification and the applicableA 555/A 555M 05 (2009)2product specification, a retest sample of two specimens may betested to replace each failed specimen of the original sample. Ifone of the retes

36、t specimens fails, the lot shall be rejected.10. Retreatment10.1 Where failure of any lot is due to inadequate heattreatment, the material may be reheat treated and resubmittedfor test.TABLE 1 Product Analysis TolerancesNOTE This table specifies tolerances over the maximum limits or under the minimu
