1、Designation: A 102 04Standard Specification forFerrovanadium1This standard is issued under the fixed designation A 102; 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 th
2、e year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers one grade of ferrovanadium.1.2 The values given in inch-pound units are to be regardedas the standard. The values given in parentheses are fo

General Conditions for Delivery3.1 Materials furnished to this specification shal
4、l conform tothe requirements of Specification A 1025, including anysupplementary requirements that are indicated in the purchaseorder. Failure to comply with the general requirements ofSpecification A 1025 constitutes nonconformance with thisspecification. In case of conflict between the requirement
5、s ofthis specification and Specification A 1025, this specificationshall prevail.3.2 Although ferrovanadium is ordered by total net weight,the customary basis of payment is per pound of containedvanadium.4. Chemical Composition4.1 The material shall conform to the requirements as tochemical composit
6、ion specified in Table 1.4.2 The manufacturer shall furnish an analysis of eachshipment showing the percentage of each element specified.5. Size5.1 The grade is available in sizes as listed in Table 2.NOTE 1The sizes listed in Table 2 are typical as shipped from themanufacturers plant. Ferrovanadium
7、 has a friability code number of “1”.It is a tough material, susceptible to little, if any, breakage during shipmentor handling.6. Chemical Analysis6.1 The chemical analysis of the material shall be made inaccordance with the procedure for ferrovanadium as describedin Test Methods E 365 or alternati
8、ve methods which will yieldequivalent results. For elements other than vanadium thechemical analysis shall be agreed upon by the purchaser andsupplier.6.2 If alternative methods of analysis are used, in case ofdiscrepancy, Test Methods E 365 shall be used for referee.6.3 Where no method is given for
9、 the analysis for aparticular element, the analysis shall be made in accordancewith a procedure agreed upon by the manufacturer and thepurchaser.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel, and Related Alloys and is the direct responsibility of Subcom
