Materials and Manufacture6.1
20、 Materials:6.1.1 The material of manufacture shall be UNS Alloy No.C17500 or C17510, cast and worked into tubular form, and ofsuch purity and soundness as to be suitable for processing intothe products prescribed herein.6.1.2 The tube shall have heat traceable identity.6.2 Manufacture:6.2.1 The prod
21、uct shall be manufactured by a combinationof hot working or cold working, or both; annealing; orprecipitation heat treatment, or both, as to produce a uniformwrought structure in the finished product, to meet the temperspecified.7. Chemical Composition7.1 The material shall conform to the chemical c
22、ompositionrequirements in Table 1 for the copper alloy designated in theordering information.7.2 These composition limits do not preclude the presenceof other elements. By agreement between the manufacturer andpurchaser, limits may be established and analysis required forunnamed elements7.3 For allo
23、ys in which copper is listed as “Remainder,”copper is the difference between the sum of results of allelements determined and 100 %. When all elements in Table 1are determined, the sum of results shall be 99.5 % min.8. Temper8.1 Tempers, as described in Classification B601, availableunder this speci
24、fication are: TB00 (solution treated (A), TF00(precipitation hardened (AT), TD04 (solution heat-treated andcold worked: hard (H), and TH04 (hard and precipitationheat-treated (HT). These products meet property requirementsin Table 2.9. Precipitation Heat Treatment9.1 When material is purchased in th
