Chemical Composition5.1 The grades of titanium and titanium alloy metal coveredby this specification shall conform to the requirements as tochemical composition prescribed in Table 1.5.1.1 The element

26、s listed in Table 1 are intentional alloyadditions or elements which are inherent to the manufacture oftitanium sponge, ingot or mill product.5.1.1.1 Elements other than those listed in Table 1 aredeemed to be capable of occurring in the grades listed in Table1 by and only by way of unregulated or u

27、nanalyzed scrapadditions to the ingot melt. Therefore, product analysis forelements not listed in Table 1 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 re

28、ported in the chemical analysis.5.2 When agreed upon by the producer and 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 notbro

29、aden the specified heat analysis requirements, but covervariations between laboratories in the measurement of chemi-cal content. The manufacturer shall not ship material which isoutside the limits specified in Table 1 for the applicable grade.Product analysis limits shall be as specified in Table 3.

30、6. Mechanical Properties6.1 Material supplied under this specification shall conformto the mechanical property requirements given in Table 2,asapplicable.6.2 Tension testing specimens are to be machined and testedin accordance with Test Methods E8. Tensile properties shallbe determined using a strai

31、n 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.3For referenced ASTM standards, visit the ASTM website, www.astm.org, orcontact ASTM Customer Service at serviceastm.org.
