S.government, this shall be specified in the contract or purchaseorder, and the material shall conform to the SupplementaryRequirements as defined in the current issue of SpecificationB 251.6. Materials and
20、Manufacture6.1 Material:6.1.1 The material of manufacture shall be Alloy C17200,cast and worked into tubular form, and of such purity andsoundness as to be suitable for processing into the productsprescribed herein.6.1.2 The tube shall have heat traceable identity.6.2 ManufactureThe product shall be
21、 manufactured by acombination of hot and cold working, annealing, or precipita-tion heat treatment, or both, as to produce a uniform wroughtstructure in the finished product, to meet the temper specified.7. Chemical Composition7.1 The material shall conform to the chemical requirementsshown in Table
22、 1.7.2 These composition limits do not preclude the presenceof other elements. Limits may be established and analysisrequired for unnamed elements by agreement between themanufacturer and purchaser. Copper may be given as remain-der and may be taken as the difference between the sum of allelements a
23、nalyzed and 100 %. When all elements in Table 1 areanalyzed, their sum shall be 99.5 % minimum.8. Temper8.1 Tempers available under this specification are solutionheat-treated TB00 (A) and cold drawn hard TD04 (H), to beprecipitation heat-treated by the user (see Table 2). Alsoavailable are products
24、 already precipitation heat-treated by themanufacturer, tempers TF00 (AT) and TH04 (HT). Theseproducts meet property requirements in Table 3 and normallyrequire no further heat treatment by the user.8.2 Tempers available under this specification are defined inClassification B 601.9. Precipitation He
25、at Treatment9.1 When material is purchased in the TB00(A) or theTD04(H) tempers, the precipitation heat treatment is per-formed by the purchaser.9.2 When testing for conformance to the TF00(AT) and theTH04(HT) property requirements shown in Table 3 for prod-ucts supplied in the TB00(A) and TD04(H) t
26、empers, theappropriate test specimens shall be heat treated for times andtemperatures within those stated in Table 4. The times andtemperatures used by the manufacturer to qualify the materialwill be stated on the mill test report. The use of other times andtemperatures, within the allowable ranges,
27、 shown in Table 4,may produce properties other than those stated on the mill testreport. This will not be cause for rejection.9.3 This material may be heat-treated at other times andtemperature for specific applications. These special combina-tions of properties, such as increased ductility, dimensi
28、onalaccuracy, endurance life, may be obtained by specialprecipitation-hardening heat treatments. The mechanical re-quirements of Table 3 do not apply to such special heattreatments. Specific test requirements as needed shall be agreedupon between the manufacturer, or supplier, and the purchaserof th
29、e end product.9.4 TF00 (AT) and TH04 (HT) tempers are standard mill-hardened products that have been precipitation heat-treated andtested by the manufacturer. An appropriate time and tempera-ture has been used to produce properties within the specifica-tion limits shown in Table 3. Table 4 does not
30、apply. Further,thermal treatments of these tempers is not normally required.10. Physical Property Requirements10.1 Microstructure and Grain Size10.1.1 The product in the precipitation heat-treated condi-tion shall have a microstructure with a minimum of secondphase (beta) constituents.10.1.2 Grain s
31、ize, if required, shall be agreed upon betweenthe purchaser and the manufacturer or the supplier and shall bedetermined in accordance with Test Methods E112.11.

35、 any two, but not all three, of the following: outsidediameter, inside diameter, wall thickness.NOTE 1Blank spaces in the tolerance tables indicate either that thematerial is not generally available or no tolerances have been established.12.2 Wall-Thickness TolerancesWall-thickness tolerancesshall b
