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 reinforc

3、ement 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 permeabi

4、lity,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 in

5、 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 conforming

6、 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 designationsar

8、 usually 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

9、 magnetic 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 W

11、 wire reinforcement.1.5 The values stated in either SIinch-pound units or inch-poundSI units are to be regarded separately as standard. Within thetext, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shallbe used independently

12、 of the other. Combining values from the two systems may result in non-conformance with the standard.2.
