ASTM A101 - 04 (2014).pdf

Designation A101 − 04 Reapproved 2014Standard Specification forFerrochromium1This standard is issued under the fixed designation A101; 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 year of last reapproval. Asuperscript epsilon indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers two types of ferrochromiumdesignated as high carbon and low carbon, the latter includingnitrogen-bearing and vacuum grades.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2. Referenced Documents2.1 ASTM Standards2A1025 Specification for Ferroalloys and Other AlloyingMaterials, General RequirementsE363 Test Methods for Chemical Analysis of Chromium andFerrochromium3. General Conditions for Delivery3.1 Materials furnished to this specification shall conform tothe requirements of Specification A1025, including any supple-mentary requirements that are indicated in the purchase order.Failure to comply with the general requirements of Specifica-tion A1025 constitutes nonconformance with this specification.In case of conflict between the requirements of this specifica-tion and Specification A1025, this specification shall prevail.4. Chemical Composition4.1 The grades shall conform to the requirements as tochemical composition specified in Table 1. The manufacturershall furnish an analysis of each shipment showing the ele-ments 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 typical, as shipped fromthe manufacturer’s 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, 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 A1025.6. Chemical Analysis6.1 The chemical analysis method shall be agreed upon bythe purchaser and supplier.6.2 In cases of discrepancy, Test Methods E363 shall beused for referee purposes.7.
