1、Designation: A483/A483M 10Standard 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 number in parentheses
2、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 separately as stand
3、ard. 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 in SI units (withi
4、n 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.

8、 specified in Table 2 on acumulative basis over a period mutually agreed upon by themanufacturer and the purchaser.5. Size5.1 The various grades are available in sizes as listed inTable 3.5.2 The sizes listed in Table 3 are typical as shipped fromthe manufacturers plant. These alloys exhibit varying
9、 degreesof friability; therefore, some attrition may be expected intransit, storage, and handling.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.18 on Castings.Current edition approve
