ASTM B98-13(R2019) pdf free download.Standard Specification for Copper-Silicon Alloy Rod, Bar and Shapes
1. Scope
1.1 This specification establishes requirements for copper- silicon rod, bar, and shapes for UNS Copper Alloys C65100, C65500, and C66100. N OTE 1—Material for hot forging is covered by Specification B124/ B124M. N OTE 2—For ASME Boiler and Pressure Vessel Code applications, see Specification SB-98 in Section II of that code. 1.2 Units—The values stated in either SI units or inch- pound units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other and values from the two systems shall not be combined. 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 Requirements
3.1 The following sections of Specification B249/B249M constitute a part of this specification: 3.1.1 Terminology; 3.1.2 Materials and Manufacture; 3.1.3 Workmanship, Finish, and Appearance; 3.1.4 Sampling; 3.1.5 Number of Tests and Retests; 3.1.6 Specimen Preparation; 3.1.7 Test Methods; 3.1.8 Significance of Numerical Limits; 3.1.9 Inspection; 3.1.10 Rejection and Rehearing; 3.1.11 Certification; 3.1.12 Test Reports; 3.1.13 Packaging and Package Marking; and 3.1.14 Supplementary Requirements. 3.2 In addition, when a section with a title identical to one of those referenced in 3.1 appears in this specification, it contains additional requirements that supplement those which appear in Specification B249/B249M.
4. Ordering Information
4.1 Include the following specified choices when placing orders for product under this specification, as applicable: 4.1.1 ASTM Designation and year of issue;4.1.2 Copper Alloy UNS No. designation; 4.1.3 Temper designation (see Temper Section 7); 4.1.4 Quantity; total weight or length, or number of pieces of each temper, form, or alloy; 4.1.5 Dimensions; diameter or distance between parallel surfaces; 4.1.6 Type of edge; edge contours; 4.1.7 How furnished; specific lengths with or without ends; and 4.1.8 Intended application. 4.2 The following options are available but may not be included unless specified at the time of placing of the order when required: 4.2.1 Certification (Specification B249/B249M), and 4.2.2 Mill Test Report (Specification B249/B249M). 4.2.3 Tensile test required for alloys in Table 4 or Table 5 (see, 4.2.4 If product is purchased for agencies of the U.S. Government (see Supplementary Requirements in Specifica- tion B249/B249M).
5. Material and Manufacture
5.1 Materials—The starting material shall be cast billets or rods of Copper Alloy UNS Nos. C65100, C65500, or C66100, and shall be of such soundness and structure as to enable them to be processed into the product specified in the contract or purchase order. 5.2 Manufacture—The product shall be manufactured by such hot-working, cold-working, straightening, and annealing processing as to produce a uniform wrought structure and obtain the required finish properties.
6. Chemical Composition
6.1 The material shall conform to the chemical requirements specified in Table 1 for the Copper Alloy UNS No. designated in the ordering information. 6.1.1 For alloys in which copper is listed as “remainder,” copper is the difference between the sum of the results of all elements determined and 100 %. 6.1.2 When all elements listed in Table 1 are determined for the designated alloy, the sum of results shall be 99.5 % min. 6.2 These composition limits do not preclude the presence of other elements. Limits may be established and analysis required for unnamed elements by agreement between the manufacturer and the purchaser.
8. Mechanical Property Requirements
8.1 Product furnished under this specification shall conform to the tensile and hardness requirements prescribed in Tables 2-5 for the Copper Alloy UNS No. designation specified in the ordering information. 8.1.1 Rockwell Hardness Requirement—For the alloys and tempers listed, product 0.5 in. [12 mm] and over in diameter or in the distance between parallel surfaces shall conform with the requirements given in Table 4 and Table 5, when tested in accordance with Test Methods E18. For the alloys and tempers listed in Table 4 and Table 5, Rockwell hardness shall be the basis of acceptance or rejection for mechanical properties except when the tensile test is specified in the contract or purchase order. 8.1.2 Tensile Strength Requirements—The product shall conform with the requirements of Table 2 and Table 3 when tested in accordance with Test Methods E8/E8M. The tensile requirements for all alloys and forms of M20 and M30 tempers shall be as agreed upon between the manufacturer and purchaser at the time of order.
