Scope

1.1 This specification covers the requirements for 28 grades of titanium and titanium alloy tubing intended for surface condensers, evaporators, and heat exchangers, as follows:

1.1.1 Grade 1 Unalloyed titanium,

1.1.2 Grade 2Unalloyed titanium,

Grade 2 H

Unalloyed titanium (Grade 2 with 58 ksi minimum UTS),

1.1.3 Grade 3 Unalloyed titanium,

1.1.4 Grade 7 Unalloyed titanium plus 0.12 to 0.25 % palladium,

Grade 7H

Unalloyed titanium plus 0.12 to 0.25 % palladium (Grade 7 with 58 ksi minimum UTS),

1.1.5 Grade 9 Titanium alloy (3 % aluminum, 2.5 % vanadium),

1.1.6 Grade 11 Unalloyed titanium plus 0.12 to 0.25 % palladium,

1.1.7 Grade 12 Titanium alloy (0.3 % molybdenum, 0.8 % nickel),

1.1.8 Grade 13 Titanium alloy (0.5 % nickel, 0.05 % ruthenium),

1.1.9 Grade 14 Titanium alloy (0.5 % nickel, 0.05 % ruthenium),

1.1.10 Grade 15 Titanium alloy (0.5 % nickel, 0.05 % ruthenium),

1.1.11 Grade 16Unalloyed titanium plus 0.04 to 0.08 % palladium,

Grade 16

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

1.1.12 Grade 17Unalloyed titanium plus 0.04 to 0.08 % palladium,

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

1.1.14 Grade 26 Unalloyed titanium plus 0.08 to 0.14 % ruthenium,

Grade 26 H

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

1.1.15 Grade 27Unalloyed titanium plus 0.08 to 0.14 % ruthenium,

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

1.1.17 Grade 30T itanium alloy (0.3 % cobalt, 0.05 % palladium),

1.1.18 Grade 31 Titanium alloy (0.3 % cobalt, 0.05 % palladium),

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

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

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

1.1.22 Grade 36Titanium alloy (45 % niobium),

1.1.23 Grade 37 Titanium alloy (1.5 % aluminum), and

1.1.24 Grade 38Titanium alloy (4 % aluminum, 2.5 % vanadium, 1.5 % iron).

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.

1.2 Tubing covered by this specification shall be heat treated by at least a stress relief as defined in .

1.3 The 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.
