ASTM B936-2019 pdf free download.Standard Specification for Copper-Chromium-Iron-Titanium Alloy Plate, Sheet, Strip and Rolled Bar
1. Scope
1.1 This specification establishes the requirements for Cop- per Alloy UNS No. C18080 for plate, sheet, strip, and rolled bar. N OTE 1—Since Copper Alloy UNS No. C18080 is frequently used in a variety ofapplications where yield strength and stress-corrosion resistance may be critical, it is recommended that drawings or samples of the part to be fabricated and details ofapplication be submitted for use in establishing temper and treatment of material. N OTE 2—Copper Alloy UNS No. C18080 is covered by a patent. Interested parties are invited to submit information regarding the identi- fication of an alternative(s) to this patented item to ASTM International headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, 1 which you may attend. 1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 Requirements
3.1 The following sections of Specifications B248 and B248M 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, except for chemical analysis; 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 Report; 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 that referenced in 3.1, above, appears in this specification, it contains additional requirements which supplement those ap- pearing in Specifications B248 and B248M.
5. Ordering Information
5.1 Include the following specified choices when placing orders for product under this specification, as applicable: 5.1.1 ASTM designation and year of issue; 5.1.2 Copper [Alloy] UNS No. (or other internationally recognized copper [alloy]) designation; 5.1.3 Temper (Section 8); 5.1.4 Dimensions, thickness, width, edges (see Section 11), and length, if applicable; 5.1.5 How furnished: straight lengths or coils; 5.1.6 Quantity—total weight or total length or number of pieces of each size; and 5.1.7 Intended application. 5.2 The following options are available but may not be included unless specified at the time of placing of the order, when required. 5.2.1 Heat identification or traceability details, 5.2.2 If product is purchased for agencies of the U.S. Government, see the Supplementary Requirements section of Specifications B248 and B248M.
6. Materials and Manufacture
6.1 Materials: 6.1.1 The material of manufacture shall be a form (cast bar, cake, slab, etc.) of Copper Alloy UNS No. C18080 of such purity and soundness as to be suitable for processing into the products prescribed herein. 6.1.2 When specified in the contract or purchase order that heat identification or traceability is required, the purchaser shall specify the details desired. N OTE 3—Due to the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify a specific casting analysis with a specific quantity of finished material. 6.2 Manufacture: 6.2.1 The product shall be manufactured by such hot working, cold working, and annealing processes as to produce a uniform wrought structure in the finished product. 6.2.2 The product shall be hot or cold worked to the finished size, and subsequently annealed when required, to meet the temper properties specified. 6.3 Edges: 6.3.1 Slit edges shall be furnished unless otherwise speci- fied in the contract or purchase order.
7. Chemical Composition
7.1 The material shall conform to the chemical composition requirements in Table 1. 7.2 These composition limits do not preclude the presence ofother elements. By agreement between the manufacturer and purchaser, limits may be established and analysis required for unnamed elements. 7.3 For alloys in which copper is listed as “Remainder,” copper is the difference between the sum of results of all elements determined and 100 %. When all elements in Table 1 are determined, the sum of the results shall be 99.8 % min.
