ASTM A482/A482M-11(2016)

Standard Specification for Ferrochrome-Silicon

ABSTRACT
This specification covers ferrochrome-silicon of Grades A and B. Chemical analysis shall be performed wherein specimens shall conform to required chemical composition of chromium, carbon, silicon, sulfur, phosphorus, nitrogen, manganese, nickel, vanadium, copper, molybdenum, columbium, tantalum, cobalt, aluminum, titanium, zirconium, arsenic, lead, tin, zinc, boron, antimony, silver, and bismuth.
SCOPE
1.1 This specification covers several grades of ferrochrome-silicon.  
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.  
1.2.1 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.  
1.2.2 Within the text, the SI units are shown in brackets.

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.

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 The values shown in Table 2 are expected maximums. Upon request of the purchaser, the manufacturer shall furnish an

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. A quantitative test is not available for rating
relative friability of ferroalloys. A code system has been developed, therefore, for this purpose, and a number rating each product
type is shown in the last column of Table 3. Definitions applicable to these code numbers are given in Specification A1025.
