(Specification)Standard Specification for Aluminum for Use in Iron and Steel Manufacture
Standard Specification for Aluminum for Use in Iron and Steel Manufacture
SCOPE
1.1 This specification covers aluminum and aluminum alloys in the form of ingots, bars, rods, cones, nuggets or shot, designated as shown in Table 1, for use in the manufacture of iron and steel.
1.2 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units, which 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 and health practices and determine the applicability of regulatory limitations prior to use.
