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 A supplementary requirement (S1) is provided and shall apply only when specified by the purchaser. In order to obtain acorrosion tested or controlled
5、magnetic permeability product, steel conforming to Supplementary Requirement S1 should beordered.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.

Examples of austenitic stainless steelsas steel designations are Type 304 S30400, 304LS30403, 316 S31600, 316LS31603, 316N S31651, 316LN S31653 andexamples of d
7、uplex stainless steels, Types steel designations are Type 2205 S32205 and 329 S32900.NOTE 1Only austenitic and duplex stainless steels are usually recommended for use as reinforcement in concrete because of their high corrosionresistance. Austenitic stainless steels have good general corrosion resis
8、tance, strength characteristics which can be improved by cold working, goodtoughness and ductility properties at low temperatures, and low magnetic permeability. Duplex stainless steels have generally a corrosion resistancegreater than that of most austenitic steels and are magnetic. Other stainless
9、 steels with different chemical compositions than the series and types mentionedabove, may be used for less restrictive applications.1.4 Wire for welded wire reinforcement is generally manufactured at 75 ksi 520 MPa yield strength level. Other strength levelsshall be by agreement between the purchas
10、er and manufacturer.NOTE 2The term used to refer to yield strength levels are the same as those in ASTM Standards for welded wire reinforcement.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.
11、The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems may result in non-conformance with the standard.2. Referenced Documents2.1 ASTM Standards:2A276 Specification for Stainless Steel Bars
