Also listed are importantresidual elements.Analysis for elements not listed
28、in Table 1 isnot required to verify compliance with this specification.7.2 Product Analysis:7.2.1 Product analysis tolerances do not broaden the speci-fied heat analysis requirements but cover variations betweenlaboratories in the measurement of chemical content. Themanufacturer shall not ship mater
29、ial that is outside the limitsspecified in Table 1. The product analysis tolerances shallconform to the product tolerances in Table 2.7.2.2 The product analysis is either for the purpose ofverifying the composition of a heat or manufacturing lot or todetermine variations in the composition within th
30、e heat.7.2.3 Acceptance or rejection of a heat or manufacturing lotof material may be made by the purchaser on the basis of thisproduct analysis. Product analyses outside the tolerance limitsallowed in Table 2 are cause for rejection of the product. Areferee analysis may be used if agreed upon by th

The utmost care must be used insampling tita
33、nium for chemical analysis because of its affinityfor elements such as oxygen, nitrogen, and hydrogen. Incutting samples for analysis, therefore, the operation should becarried out insofar as possible in a dust-free atmosphere.Cutting tools should be clean and sharp. Samples for analysisshould be st
34、ored in suitable containers.8. Mechanical Requirements8.1 The material supplied under this specification shallconform to the mechanical property requirements in Table 3 orTable 4.8.2 Specimens for tension tests shall be machined and testedin accordance with Test Methods E8/E8M. Tensile propertiessha
35、ll be determined using a strain rate of 0.003 to 0.007in./in./min mm/mm/min through the specified yield and thenthe crosshead speed shall be increased so as to produce fracturein approximately one additional minute.8.3 For sheet and strip, the bend test specimen shall with-stand being bent cold thro
36、ugh an angle of 105 without fracturein the outside surface of the bend portion. The bend shall bemade over a mandrel with a diameter equal to that shown inTable 4. Test conditions shall conform to Test Method E290.8.4 Number of Tests:8.4.1 Bar, Forging Bar, Shapes, and WireTest accordingto Test Meth
37、ods E8/E8M. Perform at least one tension testfrom each lot in the longitudinal direction. Should any testspecimen not meet the specified requirements, test two addi-tional test pieces representative of the same lot, in the samemanner, for each failed test specimen. The lot shall beconsidered in comp
38、liance only if all additional test pieces meetthe specified requirements.8.4.2 Tensile test results for which any specimen fracturesoutside the gauge length shall be considered acceptable if boththe elongation and the reduction of area meet the minimumrequirements specified. Refer to sections 7.11.4
39、 and 7.12.5 ofTest Methods E8/E8M. If either the elongation or reduction ofarea is less than the minimum requirement, discard the test andretest. Retest one specimen for each specimen that did not meetthe minimum requirements.8.4.3 Sheet, Strip, and PlateTest according to Test Meth-ods E8/E8M. Perfo
40、rm at least one tension test from each lot inthe longitudinal direction. Perform at least one bend test fromeach lot in both the longitudinal and transverse directions.Testsin the transverse direction need be made only on product fromwhich a specimen not less than 8.0 in. (200 mm) in length forsheet
41、, and 2.50 in. (64 mm) in length for plate can be taken.Should any of these test pieces not meet the specifiedrequirements, test two additional test pieces representative ofthe same lot, in the same manner, for each failed test specimen.The lot shall be considered in compliance only if all additiona
42、ltest pieces meet the specified requirements.9. Dimensions, Mass, and Permissible Variations9.1 Units of Measure:9.1.1 SelectionThis specification requires that the pur-chaser select the units (SI or inch-pound) to be used for productcertification. In the absence of a stated selection of units on th
43、epurchase order, this selection may be expressed by the pur-chaser in several alternate forms listed in order of precedence.9.1.1.1 If the purchaser and supplier have a history of usingspecific units, these units shall continue to be certified untilexpressly changed by the purchaser.9.1.1.2 In the a
44、bsence of historic precedence, if the unitsused to define the product on the purchasers PO, specification,and engineering drawing are consistent, these units shall beused by the supplier for product certification.9.1.1.3 If the purchasers selection of units is unclear, theunits of measure shall be a
