Anotácia textu normy ASTM A1022/A1022M-22a :
This specification covers stainless steel wire and welded wire reinforcements from hot-rolled stainless steel rod to be used as concrete reinforcement with corrosion resistant and magnetic permeability properties. The material shall be cold-worked, drawn or rolled, and plain or deformed. Materials shall adhere to deformation requirements. Tensile, yield, and weld shear strengths shall be measured. Bend tests shall also be performed. Dimensional requirements and permissible variations in width, length, weight, density, cross-sectional area, diameter, and average spacings of wires are specified. Guidelines for sampling, inspection, rejection, retest, certification, and packaging are given.

1.1?This specification covers stainless steel wire and welded wire reinforcement 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 and plain. It is used as concrete reinforcement for applications requiring resistance to corrosion or controlled magnetic permeability, or both. Common wire sizes and dimensions are found in this specification. Actual wire sizes are not restricted to those shown in the tables. 1.2?A supplementary requirement (S1) is provided and shall apply only when specified by the purchaser. In order to obtain a corrosion tested or controlled magnetic permeability product, steel conforming to Supplementary Requirement S1 should be ordered. 1.3?The chemical composition of the steel (stainless alloy) shall be selected for suitability to the application involved by agreement between the manufacturer and the purchaser. Unless otherwise specified by the purchaser, Specification A276 shall be used for chemical requirements. The UNS designations are to be included with the type number and noted in brackets. Examples of austenitic stainless steel designations are Type 304 [S30400], 304L [S30403], 316 [S31600], 316L [S31603], 316N [S31651], 316LN [S31653] and examples of duplex stainless steel designations are Type 2205 [S32205] and 329 [S32900]. Note 1:?Only austenitic and duplex stainless steels are
usually recommended for use as reinforcement in concrete because of
their high corrosion resistance. Austenitic stainless steels have
good general corrosion resistance, strength characteristics which
can be improved by cold working, good toughness and ductility
properties at low temperatures, and low magnetic permeability.
Duplex stainless steels have generally a corrosion resistance
greater than that of most austenitic steels and are magnetic. Other
stainless steels with different chemical compositions than the
series and types mentioned above, 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 levels shall be by agreement between the purchaser and manufacturer. Note 2:?The 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 units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification. 1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
