Designation:A1022/A1022M16bStandard Specification forDeformed and Plain Stainless Steel Wire and Welded Wirefor Concrete Reinforcement1This standard is issued under the fixed designation A1022/A1022M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers stainless steel wire and weldedwire reinforcement produced from hot-rolled stainless steelrod.The stainless steel wire is cold-worked,drawn or rolled,plain(non-deformed)or deformed or a combination of de-formed and plain.It is used as concrete reinforcement forapplications requiring resistance to corrosion or controlledmagnetic permeability,or both.Common wire sizes anddimensions are found in this specification.Actual wire sizes arenot restricted to those shown in the tables.1.2 A supplementary requirement(S1)is provided and shallapply only when specified by the purchaser.In order to obtaina corrosion tested or controlled magnetic permeability product,steel conforming to Supplementary Requirement S1 should beordered.1.3 The chemical composition of the steel(stainless alloy)shall be selected for suitability to the application involved byagreement between the manufacturer and the purchaser.Unlessotherwise specified by the purchaser,Specification A276 shallbe used for chemical requirements.The UNS designations areto be included with the type number and noted in brackets.Examples of austenitic stainless steel designations are Type304 S30400,304L S30403,316 S31600,316L S31603,316N S31651,316LN S31653 and examples of duplexstainless steel designations are Type 2205 S32205 and 329S32900.NOTE1Only austenitic and duplex stainless steels are usuallyrecommended for use as reinforcement in concrete because of their highcorrosion resistance.Austenitic stainless steels have good general corro-sion resistance,strength characteristics which can be improved by coldworking,good toughness and ductility properties at low temperatures,andlow magnetic permeability.Duplex stainless steels have generally acorrosion resistance greater than that of most austenitic steels and aremagnetic.Other stainless steels with different chemical compositions thanthe series and types mentioned above,may be used for less restrictiveapplications.1.4 Wire for welded wire reinforcement is generally manu-factured at 75 ksi 520 MPa yield strength level.Otherstrength levels shall be by agreement between the purchaserand manufacturer.NOTE2The term used to refer to yield strength levels are the same asthose in ASTM Standards for welded wire reinforcement.1.5 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in non-conformance with thestandard.2.Referenced Documents2.1 ASTM Standards:2A276 Specification for Stainless Steel Bars and ShapesA342/A342M Test Methods for Permeability of WeaklyMagnetic MaterialsA370 Test Methods and Definitions for Mechanical Testingof Steel ProductsE83 Practice for Verification and Classification of Exten-someter Systems2.2 Military Standards:3MIL-STD-129 Marking for Shipment and Storage2.3 Federal Standard:3Fed.Std.No.123 Marking for Shipments(Civil Agencies)2.4 ACI Standard:4ACI 318 Building Code Requirements for Structural Con-crete2.5 Adjuncts:Weld Tester Drawing51This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.05 on Steel Reinforcement.Current edition approved Sept.1,2016.Published September 2016.Originallyapproved in 2001.Last previous edition approved in 2016 as A1022/A1022M 16a.DOI:10.1520/A1022_A1022M-16B.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/www.dodssp.daps.mil.4Available from American Concrete Institute(ACI),P.O.Box 9094,FarmingtonHills,MI 48333-9094,http:/www.aci-int.org.5Available from ASTM International Headquarters.Order Adjunct No.ADJA0185.Original adjunct produced in 1967.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 stainless steel plain wire and welded plain wirereinforcementas used within the scope and i
