1.1.31 Grade 34—UNS R53445. Titanium alloy (0.4 %
nickel, 0.015 % palladium, 0.025 % ruthenium, 0.15 %
chromium),
1.1.32 Grade 35—UNS R56340. Titanium alloy (4.5 %

0.3 % silicon),
1.1.33 Grade 36—UNS R58450. Titanium alloy (45 %

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.
1.2 The values state in either inch-pound units or SI units
are to be regarded separately as standard. The values stated in
each system are not exact equivalents; therefore, each system
shall be used independently of the other. Combining values
from the two systems may result in nonconformance with the
speciﬁcation.
1.3 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
