1、Designation: A555/A555M 16Standard Specification forGeneral Requirements for Stainless Steel Wire and WireRods1This standard is issued under the fixed designation A555/A555M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year
2、 of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers g
3、eneral requirements that shallapply to stainless wire and wire rods. Wire rods are asemifinished product intended primarily for the manufacture ofwire. Wire is intended primarily for cold forming, includingcoiling, stranding, weaving, heading and machining as coveredunder the latest revision of each

The values stated ineach system may not be exact equi
6、valents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.6 Unless the order specifies the applicable metric specifi-cation designation, the material shall be furnished in theinch-pound units.2.

16、2 wireas covered by this specification and the speci-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 ana
17、pproximate round cross section in continuous length coils.4. Materials and Manufacture4.1 The material may be furnished in one of the conditionsdetailed in the applicable material specification, that is,annealed, bright annealed, cold worked, or as otherwise speci-fied on the purchase order.4.2 A va
18、riety of finishes, coatings, and lubricants are avail-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
19、 Heat or Cast AnalysisThe chemical analysis of eachheat shall be determined in accordance with the applicablematerial specification and Test Methods, Practices, and Termi-nology A751.5.1.1 The analysis of each heat shall be made from a testsample taken during the pouring of the melt, or from thein-p
20、rocess product later in the manufacturing flow.5.1.2 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 wh
21、ich are specified. It is neitherpractical nor necessary to specify limits for unspecified ele-ments that can be present. The producer is permitted to analyzefor unspecified elements and is permitted to report suchanalyses. The presence of an unspecified element and thereporting of an analysis for th
22、at element shall not be a basis forrejection unless the presence of that element causes the loss ofa property typically expected for that metal for the type andquality ordered.5.1.4 The purchaser is permitted to require in the purchaseorder a maximum limit for an individual element not specifiedin t
23、he 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 purchaser is permitted to make the req
24、uirementsfor 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 not permitted to make chemicalrequirem
25、ents 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 areassociated in typical methods of chemi
26、cal analysis.5.2 Product AnalysisWhen required, a product analysisshall be determined in accordance with Test Methods,Practices, and Terminology A751. The chemical compositionthus determined shall conform to the tolerances shown in Table1.5.3 The steel shall not contain an unspecified element forthe
27、 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 minimum.6. Permissible Variations in Dimensions
28、6.1 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 consistent withgood manufacturing and inspec
29、tion 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 shall consist of all wire madefrom the same hea
30、t.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-sitic grades when annealed to Condition A and
31、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 steels to Condition T or H and when age ha
32、rdening 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 otherwise specified in the product specification,o
33、ne 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 test, when required, and onegrain size tes
34、t, when required, shall be made from each lot. Itis often convenient to obtain test material from the specimenselected for mechanical testing.A555/A555M 1629.3 If any test specimen shows imperfections that may affectthe test results, it may be discarded and another specimensubstituted.9.4 If the res
35、ults of any test lot are not in conformance withthe requirements of this specification and the applicableproduct specification, a retest sample of two specimens may betested to replace each failed specimen of the original sample. Ifone of the retest specimens fails, the lot shall be rejected.10. Ret
36、reatment10.1 Where failure of any lot is due to inadequate heattreatment, the material may be reheat treated and resubmittedfor test.11.
