1、Designation: A1022/A1022M 16bStandard 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 th

2、e 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

3、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. C

4、ommon 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 permeabili

5、ty 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, Sp

6、ecification 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 duplexstai

7、nless steel designations are Type 2205 S32205 and 329S32900.NOTE 1Only 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 character

8、istics 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 chem

9、ical 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.NOTE 2Th

10、e 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 eachsyste

11、m 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.
