1.1.11Grade 15—Titanium alloy (0.5 % nickel, 0.05 % ruthenium), medium oxygen,

1.1.12Grade 16—Unalloyed titanium plus 0.04 to 0.08 % palladium, standard oxygen,

1.1.12.1Grade 16H—Unalloyed titanium plus 0.04 to 0.08 % palladium (Grade 16 with 58 ksi minimum UTS),

1.1.13Grade 17—Unalloyed titanium plus 0.04 to 0.08 % palladium, low oxygen,

1.1.14Grade 18—Titanium alloy (3 % aluminum, 2.5 % vanadium plus 0.04 to 0.08 % palladium),

1.1.15Grade 19—Titanium alloy (3 % aluminum, 8 % vanadium, 6 % chromium, 4 % zirconium, 4 % molybdenum),

1.1.16Grade 20—Titanium alloy (3 % aluminum, 8 % vanadium, 6 % chromium, 4 % zirconium, 4 % molybdenum) plus 0.04 to 0.08 % palladium,

1.1.17Grade 21—Titanium alloy (15 % molybdenum, 3 % aluminum, 2.7 % niobium, 0.25 % silicon),

1.1.18Grade 23—Titanium alloy (6 % aluminum, 4 % vanadium, extra low interstitial, ELI),

1.1.19Grade 24—Titanium alloy (6 % aluminum, 4 % vanadium) plus 0.04 to 0.08 % palladium,

1.1.20Grade 25—Titanium alloy (6 % aluminum, 4 % vanadium) plus 0.3 to 0.8 % nickel and 0.04 to 0.08 % palladium,

1.1.21Grade 26—Unalloyed titanium plus 0.08 to 0.14 % ruthenium,

1.1.21.1Grade 26H—Unalloyed titanium plus 0.08 to 0.14 % ruthenium (Grade 26 with 58 ksi minimum UTS),

1.1.22Grade 27—Unalloyed titanium plus 0.08 to 0.14 % ruthenium,

1.1.23Grade 28—Titanium alloy (3 % aluminum, 2.5 % vanadium) plus 0.08 to 0.14 % ruthenium,

1.1.24Grade 29—Titanium alloy (6 % aluminum, 4 % vanadium with extra low interstitial elements (ELI)) plus 0.08 to 0.14 % ruthenium,

1.1.25Grade 33—Titanium alloy (0.4 % nickel, 0.015 % palladium, 0.025 % ruthenium, 0.15 % chromium),

1.1.26Grade 34—Titanium alloy (0.4 % nickel, 0.015 % palladium, 0.025 % ruthenium, 0.15 % chromium),

1.1.27Grade 35—Titanium alloy (4.5 % aluminum, 2 % molybdenum, 1.6 % vanadium, 0.5 % iron, 0.3 % silicon),

1.1.28Grade 37—Titanium alloy (1.5 % aluminum),

1.1.29Grade 38—Titanium alloy (4 % aluminum, 2.5 % vanadium, 1.5 % iron), and

1.1.30Grade 39—Titanium alloy (0.25 % iron, 0.4 % silicon).

Note 1—H grade material is identical to the corresponding numeric grade (that is, Grade 2H = Grade 2) except for the higher guaranteed minimum UTS, and may always be certified as meeting the requirements of its corresponding numeric grade. Grades 2H, 7H, 16H, and 26H are intended primarily for pressure vessel use.

The H grades were added in response to a user association request based on its study of over 5200 commercial Grade 2, 7, 16, and 26 test reports, where over 99 % met the 58 ksi minimum UTS.

1.2Pipe 8 in. NPS (nominal pipe size) and larger is most frequently custom made for an order. In such cases, the purchaser carefully should consider the applicability of this specification. Since the pipe is custom made, the purchaser may choose a wall thickness other than those in Table 1 to meet specific operating conditions. The purchaser may also be better served to specify only the portions of this specification that are required to meet the operating conditions (for example, annealing, flattening test, chemistry, properties, etc.).

Note 1—Schedule sizes conform to ANSI/ASME B 36.19M-1985 (for “S” sizes) or B 36.10 (for non-S sizes).

Note 2—The decimal thickness listed for the respective pipe sizes represent their nominal wall dimensions.

^A Threading not permitted in accordance with ANSI B.1.20.1 .

1.3Optional supplementary requirements are provided for pipe where a greater degree of testing is desired. These supplementary requirements may be invoked by the purchaser, when desired, by specifying in the order.

1.4The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
