21、 width are classified as sheet;any product over 0.187 in. (4.75 mm) in thickness and over 10in. (254 mm) in width is classified as plate.4. Ordering Information4.1 Orders for materials under this specification shall in-clude the following information as applicable:4.1.1 Grade number (Section 1),4.1.
22、2 Product limitations (Section 3),4.1.3 Special mechanical properties (Table 1),4.1.4 Marking (Section 16),4.1.5 Finish (Section 8),4.1.6 Packaging (Section 16),4.1.7 Required reports (Section 15), and4.1.8 Disposition of rejected material (Section 14).5. Chemical Composition5.1 The grades of titani
23、um 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 are inherent to the manufacture oftitanium sponge, ingot or mill product.5.1.1.1
24、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 analysis forelements not listed in Table 2 shall not be required unlessspecified and sh
25、all 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 purchaser andrequested by the purchaser in his written purchase order,chemical a
26、nalysis 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 between laboratories in the measurement of chemi-cal content. The manufacturer shall no
27、t 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 chemical composition. Samples shall betaken from the ingot or the extremes of th
28、e 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 are to be machined and testedin accordance with Test Methods E8. Tensile propertie
29、s 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 strip, the bend test specimen shall with-stand being bent cold through an angle of
30、105 without fracturein the outside of the bent portion. The bend shall be made ona diameter equal to that shown in Table 1 for the applicablegrade.7. Permissible Variations in Dimensions7.1 Dimensional tolerances on titanium and titanium alloymaterial covered by this specification shall be as specif
31、ied inTables 4-13, as applicable.8. Finish8.1 Titanium and titanium 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 a
32、s ground, or both sandblasted and ground. If3For referenced ASTM standards, visit the ASTM website, www.astm.org, orcontact ASTM Customer Service at serviceastm.org. For Annual Book of ASTMStandards volume information, refer to the standards Document Summary page onthe ASTM website.B 265 08a2shipped
33、 as descaled, 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 Samp
34、les for chemical 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 ca
35、rried out 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.10. Methods of Chemical Analysis10.1 The chemical analysis shall normally be conductedusing theASTM stand
36、ard test methods referenced in 2.1. Otherindustry standard methods may be used where the ASTM testmethods in 2.1 do not adequately cover the elements in thematerial or by agreement between the producer and purchaser.Alternate techniques are discussed in Guide E 2626.TABLE 1 Tensile RequirementsAGrad
