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.

Silicomanganese
This standard is issued under the fixed designationA483/A483M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number 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.
1.2The 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.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values 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.

however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units
shall apply.

2.1 ASTM Standards:
A1025 Specification for Ferroalloys and Other Alloying Materials, General Requirements
E11 Specification for Woven Wire Test Sieve Cloth and Test Sieves
3. General Conditions for Delivery
3.1 Materials furnished to this specification shall conform to the requirements of Specification A1025, including any
supplementary requirements that are indicated in the purchase order. Failure to comply with the general requirements of
Specification A1025 constitutes nonconformance with this specification. In case of conflict between the requirements of this
specification and Specification A1025, this specification shall prevail.
4. Chemical Composition
4.1 The various grades shall conform to the requirements as to chemical composition specified in Tables 1 and 2.
4.2 The manufacturer shall furnish an analysis of each shipment showing the percentage of each element specified in Table 1.
4.3 Upon request of the purchaser, the manufacturer shall furnish an analysis for the elements specified in Table 2 on a
cumulative basis over a period mutually agreed upon by the manufacturer and the purchaser.
5. Size
5.1 The various grades are available in sizes as listed in Table 3.
5.2 The sizes listed in Table 3 are typical as shipped from the manufacturer’s plant. These alloys exhibit varying degrees of
friability; therefore, some attrition may be expected in transit, storage, and handling.
