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.
