Chemical Composition5.1 The grades of titanium and titanium alloy metal coveredby this specification shall conform to the chemical compositionrequirements prescribed in Table 2.5.1.1 The elements listed in Table 2 are intentional alloyadditions or elements which
24、are inherent to the manufacture oftitanium sponge, ingot or mill product.5.1.1.1 Elements other than those listed in Table 2 aredeemed to be capable of occurring in the grades listed in Table2 by and only by way of unregulated or unanalyzed scrapadditions to the ingot melt. Therefore, product analys
25、is forelements not listed in Table 2 shall not be required unlessspecified and shall be considered to be in excess of the intentof this specification.5.1.2 Elements intentionally added to the melt must beidentified, analyzed, and reported in the chemical analysis.5.2 When agreed upon by producer and
26、 purchaser andrequested by the purchaser in his written purchase order,chemical analysis shall be completed for specific residualelements not listed in this specification.5.3 Product AnalysisProduct analysis tolerances do notbroaden the specified heat analysis requirements but covervariations betwee
27、n laboratories in the measurement of chemi-cal content. The manufacturer shall not ship material that isoutside the limits specified in Table 2 for the applicable grade.Product analysis limits shall be as specified in Table 3.5.4 At least two samples for chemical analysis shall betested to determine
28、 chemical composition. Samples shall betaken from the ingot or the extremes of the product to beanalyzed.6. Mechanical Properties6.1 Material supplied under this specification shall conformto the mechanical property requirements given in Table 1 forthe grade specified.6.2 Tension testing specimens a
29、re to be machined and testedin accordance with Test Methods E8. Tensile properties shallbe determined using a strain rate of 0.003 to 0.007 in./in./minthrough the specified yield strength, and then increasing therate so as to produce failure in approximately one additionalminute.6.3 For sheet and st
30、rip, the bend test specimen shall with-stand being bent cold through an angle of 105 without fracturein the outside of the bent portion. The bend shall be made ona radius equal to that shown in Table 1 for the applicablegrade. The bends are to be made in accordance with TestMethod E 290, using Metho
31、d 1, Guided Bend Test described inparagraph 3.6, bent through 105, and allowed to spring backnaturally. The surface of the specimen must include the originalmaterial surface with no material removal or surface condi-tioning, except corners may be rounded to a maximum radiusof 0.032 in. (0.8 mm). The
32、 width of the bend shall be at least5 times the thickness. The test report shall, at minimum,indicate acceptable or unacceptable results.7. Permissible Variations in Dimensions7.1 Dimensional tolerances on titanium and titanium alloymaterial covered by this specification shall be as specified inTabl

For Annual Book of ASTMStandards volume information, refer to the standards Document Summary page onthe ASTM website.B 265 08b28. Finish8.1 Titanium and ti
34、tanium alloy sheet, strip, and plate shallbe free of injurious external and internal imperfections of anature that will interfere with the purpose for which it isintended. Annealed material may be furnished as descaled, assandblasted, or as ground, or both sandblasted and ground. Ifshipped as descal
35、ed, sandblasted, or ground, the manufacturershall be permitted to remove minor surface imperfections byspot grinding if such grinding does not reduce the thickness ofthe material below the minimum permitted by the tolerance forthe thickness ordered.9. Sampling for Chemical Analysis9.1 Samples for ch
36、emical analysis shall be representative ofthe material being tested. The utmost care must be used insampling titanium for chemical analysis because of its greataffinity for elements such as oxygen, nitrogen, and hydrogen.Therefore, in cutting samples for analysis, the operation shouldbe carried out
37、insofar as possible in a dust-free atmosphere.Chips should be collected from clean metal and tools should beclean and sharp. Samples for analysis should be stored insuitable containers.TABLE 1 Tensile RequirementsAGradeTensile Strength, min Yield Strength, 0.2 % OffsetElongation in2 in. or 50 mm,min
