1、Designation: A483/A483M 10 (Reapproved 2015)Standard Specification forSilicomanganese1This standard is issued under the fixed designation A483/A483M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A numb

2、er in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers grades of silicomanganese.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded s

3、eparately as standard. Thevalues 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.1.2.1 This specification is expressed in both inch-poundunits and

4、in SI units (within the text, the SI units are shown inbrackets); however, unless the purchase order or contractspecifies the applicable M specification designation (SI units),the inch-pound units shall apply.2.
