This specification covers the requirements for wrought titanium-6aluminum-4vanadium alloy for use in surgical implant applications. The material shall be manufactured by multiple melting in plasma arc and electron beam furnaces into strip, sheet, plate, bar, forging bar, or wire. The material shall be available in the annealed or cold-worked condition, with the surface mechanically descaled or pickled, sandblasted, chemically milled, ground, machined, peeled, polished, or a combination of these. Heat and product analyses as well as tension and bend (for sheet, strip, and plate) tests shall be performed and shall conform to the requirements specified. In addition, the material shall have a microstructure consisting of a fine dispersion of alpha and beta phases as a result of processing in the alpha plus beta field, with no continuous alpha network at prior beta grain boundaries and no coarse, elongated alpha platelets.
1.1 This specification covers the chemical, mechanical, and metallurgical requirements for wrought annealed titanium-6aluminum-4vanadium alloy (UNS R56400) to be used in the manufacture of surgical implants.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
