1、Designation: A100 07 (Reapproved 2018)Standard Specification forFerrosilicon1This standard is issued under the fixed designation A100; 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 parenthes

2、es indicates the year of last reapproval. Asuperscript epsilon () 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 stand

6、dicated in thepurchase order. Failure to comply with the general require-ments of Specification A1025/A1025M constitutes nonconfor-mance with this specification. In case of conflict between therequirements of this specification and Specification A1025/A1025M, this specification shall prevail.4. Chem

7、ical Composition4.1 The various grades shall conform to the requirements asto chemical 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 variou

8、s grades are available in sizes as listed inTable 2.5.2 The sizes listed in Table 2 are 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

9、 for rating relative friability of ferroalloys. A code systemhas been developed, therefore, 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 A1025/A1025M.6. Chemical Analysis6.1 Un

10、less otherwise agreed upon, the chemical analysis ofthe material shall be made in accordance with Test MethodsE360.6.2 If alternative methods of analysis are used, MethodsE360 shall be used for referee.6.3 Where a method is not given in Methods E360 for theanalysis for a particular element, the anal

11、ysis shall be made inaccordance with a procedure agreed upon between the manu-facturer and the purchaser.7.
