摘要

1.1This 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.1.2A 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.1.3The 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, SpecificationA276shall 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.1.4Wire 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.1.5The 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 standard.1.6This 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. 1.1本规范涵盖了由热轧不锈钢棒制成的不锈钢丝和焊接钢丝加强件。不锈钢丝为冷加工、拉制或轧制、普通（非变形）或变形或变形与普通的组合。它被用作需要耐腐蚀或可控磁导率的应用的混凝土钢筋，或两者兼而有之。常见导线尺寸和尺寸见本规范。实际导线尺寸不限于表中所示的尺寸。1.2提供了补充要求（S1），仅当买方规定时适用。为了获得经过腐蚀测试或控制的磁导率产品，应订购符合补充要求S1的钢材。1.3钢材（不锈钢合金）的化学成分应根据制造商和买方之间的协议进行选择，以适合所涉及的应用。除非买方另有规定，规范A276型应用于化学要求。UNS名称应包括在型号中，并在括号中注明。奥氏体不锈钢名称的示例有304[S30400]、304L[S30403]、316[S31600]、316L[S31603]、316N[S31651]、316LN[S31663]，双相不锈钢名称的实例有2205[S32205]和329[S32900]。注1:由于奥氏体和双相不锈钢具有较高的耐腐蚀性，因此通常建议将其用作混凝土中的钢筋。奥氏体不锈钢具有良好的一般耐腐蚀性、可通过冷加工提高的强度特性、良好的低温韧性和延展性以及低磁导率。双相不锈钢通常具有比大多数奥氏体钢更高的耐腐蚀性，并且具有磁性。其他化学成分不同于上述系列和类型的不锈钢可用于限制性较小的应用。1.4焊接钢丝增强用钢丝通常以75 ksi[520 MPa]屈服强度水平制造。其他强度等级应由买方和制造商商定。注2:用于表示屈服强度水平的术语与ASTM标准中焊接钢丝加固的术语相同。1.5以英寸-磅单位或国际单位表示的数值应单独视为标准值。在文本中，SI单位显示在括号中。每个系统中规定的值可能不完全相等；因此，每个系统应独立于其他系统使用。组合两个系统的值可能会导致-符合标准。1.6本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 展开▼
