1.1 本规范涵盖了碳含量通常为0.015的锻造低碳钢的要求 % 或更少，其余化学成分基本上为铁。 1.1.1 涵盖两种合金类型:类型1为低磷等级，类型2含有磷添加剂，以提高可加工性。 1.2 本规范还涵盖了制造商或转炉提供的合金，其形式和条件适合制造成零件，随后将进行热处理以产生所需的磁性。它包括以锻造坯料、热轧产品和冷加工棒材、线材和带材形式供应的合金。 1.3 本规范不包括能够加工成磁性部件的铁粉。有关粉末金属材料和磁性部件的信息，请参考以下ASTM标准: 规格 A811型 , A839 和 A904 . 1.4 本规范不包括平轧低碳电工钢。请参考规范 A726 有关这些材料的信息。 1.5 以国际单位制表示的数值应视为标准值。括号中给出的数值是到常用（cgs-emu和inch-pound）单位的数学转换，仅供参考，不被视为标准。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.7 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。

1.1 This specification covers the requirements for wrought low-carbon iron typically having a carbon content of 0.015 % or less with the remainder of the chemical composition being substantially iron. 1.1.1 Two alloy types are covered: Type 1 is a low-phosphorous grade and Type 2 contains a phosphorous addition to improve machinability. 1.2 This specification also covers alloys supplied by a producer or converter in the form and condition suitable for fabrication into parts which will be subsequently heat treated to create the desired magnetic characteristics. It covers alloys supplied in the form of forging billets, hot-rolled products, and cold-finished bar, wire, and strip. 1.3 This specification does not cover iron powders capable of being processed into magnetic components. Please refer to the following ASTM Standards for information regarding powdered metal materials and magnetic components: Specifications A811 , A839 , and A904 . 1.4 This specification does not cover flat-rolled, low-carbon electrical steels. Please refer to Specification A726 for information regarding these materials. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.7 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.
