Abstract:

This specification covers annealed titanium and titanium alloy strip, sheet, and plate. The grades of titanium and titanium alloy metal covered by this specification shall have the chemical composition requirements of: nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, tin, ruthenium, palladium, cobalt, molybdenum, chromium, nickel, niobium, zirconium, silicon, and titanium. For sheet and strip, the bend test specimen shall stand being bent cold through without fracture in the outside of the bent portion. Product analysis tolerances cover variations between laboratories in the measurement of chemical content of the specimen. In cutting samples for analysis, the operation should be carried out insofar as possible in a dust-free atmosphere because utmost care must be used in sampling titanium for chemical analysis due to its great affinity for elements such as oxygen, nitrogen, and hydrogen. The chemical analysis shall be conducted by the standard techniques normally utilized by the manufacturer and purchaser.

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 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.
