This specification covers the chemical, mechanical, and metallurgical requirements for wrought and annealed or cold-worked and stress-relieved titanium-3aluminum-2.5vanadium alloy (UNS R56320) seamless tubing to be used in the manufacture of surgical implants. The mill product shall be furnished as descaled or pickled, abrasive blasted, chemically milled, ground, machined, peeled, or polished. Conditions for annealing, cold-working and stress relieving, and surface cleanliness are specified. Heat analysis shall conform to the chemical composition requirements prescribed for: nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, yttrium, and titanium. The material shall conform to the mechanical property requirements specified for: ultimate tensile strength, yield strength, and elongation. Requirements for tension testing, microstructure, ultrasonic testing, and longitudinal and transverse notch machining are specified as well.

1.1 This specification covers the chemical, mechanical, and metallurgical requirements for wrought and annealed or cold-worked and stress-relieved titanium-3aluminum-2.5vanadium alloy (UNS R56320) seamless tubing to be used in the manufacture of surgical implants. See Section for size limitations.

1.2 The values stated in inch pound units are to be regarded as the standard. The SI equivalents in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
