Standard Specification for Aluminum for Use in Iron and Steel Manufacture
ABSTRACT
This specification covers the standard for ingot, bar, rod, cone, nugget or shot aluminum and aluminum alloys proposed for use in manufacturing iron and steel. Each sample shall conform to the chemical composition limits enlisted herein. Test samples can be taken at the time the ingots, bars, rods, cones, nuggets or shots are produced or from the finished product.
SCOPE
1.1 This specification covers aluminum-alloy deoxidizing products of all compositions in the form of ingots, bars, rods, cones, nuggets, shot, or stars, for use in the manufacture of iron and steel. Six of the most commonly used deoxidizing product compositions are designated as shown in Table 1. (A) Analysis shall be made only for copper, zinc, magnesium, silicon, and iron unless the determination of additional elements is required by the contract or order, or the presence of other elements in substantial concentration is indicated during the course of the analysis. In the latter case, the amount of these other elements shall be determined, reported, and the total of copper, zinc, magnesium, silicon, iron, and “other elements” shall not exceed the specified amount prescribed in the last column of the table. Unless otherwise specified in the contract or order, 0.2 % or more of any “other element” shall constitute a “substantial concentration” and require that element to be reported.(B) The following applies to all specified limits in this table: For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit in accordance with the rounding-off method of Practice E29.
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
