- Scope
- 1.1 This specification covers the requirements for mill-cast and wrought magnetic pure iron containing no more than 0.0060 % carbon and a typical total iron content of 99.9 %. The magnetic characteristics exhibited by magnetic pure iron are made possible by the absence of alloying elements during production. 1.2 This specification also covers magnetic pure iron supplied in a form and condition which allows for subsequent heat treatment to achieve desired magnetic characteristics. 1.3 Magnetic pure iron may be supplied in forms including hot-rolled strip, sheet, plate, bar, billet, and slab; cold-rolled strip and sheet; mill-cast slab and bloom; forgings; and drawn wire and rod. 1.4 This specification does not cover cast parts or 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 . 1.5 This specification does not cover material that contains constituent elements sufficient to increase the carbon content above 0.0060 % or to decrease the iron content below 99.9 %. Refer to Specification A848 for properties of low carbon magnetic iron. 1.6 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. 1.6.1 There are selected values presented in two units, both of which are acceptable SI units. These are differentiated by the word “or,” as in “g/cm3, or, (kg/m3).” 1.7 Acceptance values may be generated by an independent party. This specification accepts reports from producers or intermediate suppliers. 1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 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.
