1、Designation: A 100 07Standard Specification forFerrosilicon1This standard is issued under the fixed designation A 100; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the
2、 year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers grades of ferrosilicon forsteelmaking and foundry uses.1.2 The values stated in inch-pound units are to be regardedas the standard. The metric
3、 equivalents of inch-pound units (SIunits) given in parentheses may be approximate.2.

General Conditions of Delivery3.1 Materials furnished to this specification shall conform tothe requirements of Specification A 1025, including anysupplementary requirements that are indicated in the purchaseorder. Failure to comply with the general requ
5、irements ofSpecification A 1025 constitutes nonconformance with thisspecification. In case of conflict between the requirements ofthis specification and Specification A 1025, this specificationshall prevail.4. Chemical Composition4.1 The various grades shall conform to the requirements asto chemical
6、 composition prescribed in Table 1.4.2 The manufacturer shall furnish an analysis of eachshipment showing the silicon content and when required, suchof the other elements specified in Table 1.5. Size5.1 The various grades are available in sizes as listed inTable 2.5.2 The sizes listed in Table 2 are
7、 typical as shipped fromthe manufacturers plant. These alloys exhibit varying degreesof friability; therefore, some attrition may be expected intransit, storage, and handling. A quantitative test is not avail-able for rating relative friability of ferroalloys. A code systemhas been developed, theref
8、ore, for this purpose, and a numberrating for each product type is shown in the last column ofTable 2. Definitions applicable to these code numbers are givenin Specification A 1025.6. Chemical Analysis6.1 Unless otherwise agreed upon, the chemical analysis ofthe material shall be made in accordance
9、with Test MethodsE 360.6.2 If alternative methods of analysis are used, MethodsE 360 shall be used for referee.6.3 Where a method is not given in Methods E 360 for theanalysis for a particular element, the analysis shall be made inaccordance with a procedure agreed upon between the manu-facturer and
