ASTM A481-05(R2020) pdf free download.Standard Specification for Chromium Metal
1. Scope
1.1 This specification covers several grades of chromium metal. 1.2 The values stated in inch-pound units are to be regarded as the standard. 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.

3. General Conditions for 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 specified in Tables 1 and 2. 4.2 The manufacturer shall furnish an analysis of each shipment showing the elements specified in Table 1. 4.3 The values shown in Table 2 are expected maximums. Upon request of the purchaser, the manufacturer shall furnish an analysis for any of these elements on a cumulative basis over a period mutually agreed upon between the manufacturer and the purchaser.
5. Size
5.1 The various grades are available in sizes as listed in Table 3. 5.2 The sizes listed in Table 3 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 each product type is shown in the last column of Table 3. Definitions applicable to these code numbers are given in Specification A1025/A1025M.
6. Chemical Analysis
6.1 The chemical analysis of the material shall be made in accordance with the procedure for the ferroalloys as described in Test Methods E363 or alternative methods, agreed upon by the purchaser and supplier, that will yield equivalent results. 6.2 If alternative methods of analysis are used, in case of discrepancy, Test Methods E363 shall be used for referee. 6.3 Where no method is given in Test Methods E363 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.
