Titanium alloy (0.25 % iron, 0.4 % silicon).NOTE 1H grade material is identical to the corresponding numeric grade (that is, Grade 2H = Grade 2) except for the higher guaran
18、teed minimumUTS, and may always be certified as meeting the requirements of its corresponding numeric grade. Grades 2H, 7H, 16H, and 26H are intended primarilyfor pressure vessel use.1.2 Pipe 8 in. NPS (nominal pipe size) and larger is most frequently custom made for an order. In such cases, the pur
19、chasercarefully should consider the applicability of this specification. Since the pipe is custom made, the purchaser may choose a wallthickness other than those in Table 1 to meet specific operating conditions. The purchaser may also be better served to specify onlythe portions of this specificatio
20、n that are required to meet the operating conditions (for example, annealing, flattening test,chemistry, properties, etc.).1.3 Optional supplementary requirements are provided for pipe where a greater degree of testing is desired. Thesesupplementary requirements may be invoked by the purchaser, when
21、 desired, by specifying in the order.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.2. Referenced Documents2.1 ASTM Standards:2A37
