A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers stainless steel wire and welded wire reinfor
3、cement produced from hot-rolled stainless steel rod.The stainless steel wire is cold-worked, drawn or rolled, plain (non-deformed) or deformed or a combination of deformed andplain. It is used as concrete reinforcement for applications requiring resistance to corrosion or controlled magnetic permeab
4、ility,or both. Common wire sizes and dimensions are found in this specification. Actual wire sizes are not restricted to those shown inthe tables.1.2 Supplement S1 describes high strength wire, which shall be furnished when specifically ordered. It shall be permissible tofurnish high strength wire i
5、n place of regular wire if mutually agreed to by the purchaser and supplier.1.2.1 A supplementary requirement (S2) of an optional nature is provided. It shall apply only when specified by the purchaser.In order to obtain a corrosion tested or controlled magnetic permeability product, steel conformin
6、g to Supplementary RequirementS2 should be ordered.1.3 The chemical composition of the steel (stainless grade) shall be selected for suitability to the application involved byagreement between the manufacturer and the purchaser. Use Specification A276 for chemical requirements. The UNS designationsa
7、re to be included with the type number and noted in brackets, that is, austenitic stainless steels as Type 304 S30400, 304LS30403, 316 S31600, 316L S31603, 316N S31651, 316LN S31653 and duplex stainless steels, Types 2205 S32205 and329 S32900.NOTE 1Only austenitic and duplex stainless steels are usu
8、ally recommended for use as reinforcement in concrete because of their high corrosionresistance. Austenitic stainless steels have good general corrosion resistance, strength characteristics which can be improved by cold working, goodtoughness and ductility properties at low temperatures, and low mag
9、netic permeability. Duplex stainless steels have generally a corrosion resistancegreater than that of most austenitic steels and are magnetic. Other stainless steels with different chemical compositions than the series and types mentionedabove, may be used for less restrictive applications.1.4 Wire
10、for welded wire reinforcement is generally manufactured at 75 ksi 520 MPa yield strength level. Other strength levelsshall be by agreement between the purchaser and manufacturer.NOTE 2The term used to refer to yield strength levels are the same as those in ASTM Standards for welded wire reinforcemen
11、t.1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining value
