ASTM A100-2018 pdf free download.Standard Specification for Ferrosilicon
1. Scope
1.1 This specification covers grades of ferrosilicon for steelmaking and foundry uses. 1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units (SI units) given in parentheses may be approximate. 1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
2. Referenced Documents
2.1 ASTM Standards: 2 A1025/A1025M Specification for Ferroalloys and Other Al- loying Materials, General Requirements E11 Specification for Woven Wire Test Sieve Cloth and Test Sieves E360 Test Methods for Chemical Analysis of Silicon and Ferrosilicon (Withdrawn 2006)
3. General Conditions of Delivery
3.1 Materials furnished to this specification shall conform to the requirements of Specification A1025/A1025M, including any supplementary requirements that are indicated in the purchase order. Failure to comply with the general require- ments of Specification A1025/A1025M constitutes nonconfor- mance with this specification. In case of conflict between the requirements of this specification and Specification A1025/ A1025M, this specification shall prevail.
4. Chemical Composition
4.1 The various grades shall conform to the requirements as to chemical composition prescribed in Table 1. 4.2 The manufacturer shall furnish an analysis of each shipment showing the silicon content and, when required, such of the other elements specified in Table 1.
5. Size
5.1 The various grades are available in sizes as listed in Table 2. 5.2 The sizes listed in Table 2 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 avail- able for rating relative friability of ferroalloys. A code system has been developed, therefore, for this purpose, and a number rating for each product type is shown in the last column of Table 2. Definitions applicable to these code numbers are given in Specification A1025/A1025M.
6. Chemical Analysis
6.1 Unless otherwise agreed upon, the chemical analysis of the material shall be made in accordance with Test Methods E360. 6.2 If alternative methods of analysis are used, Methods E360 shall be used for referee. 6.3 Where a method is not given in Methods E360 for the analysis for a particular element, the analysis shall be made in accordance with a procedure agreed upon between the manu- facturer and the purchaser.
7. Keywords
7.1 ferroalloy; ferrosilicon
