This specification covers the chemical, mechanical, and metallurgical requirements for cast titanium-6aluminum-4vanadium alloy (UNS R56406). Castings conforming to this specification shall be produced by vacuum investment casting. Castings covered by this specification shall be in the annealed and hot isostatically pressed condition. Product castings shall conform to the requirements prescribed. Material supplied under this specification shall conform to the mechanical property requirements prescribed. Chemical analysis, product analysis, tension tests, fluorescent penetrant examination, and radiographic examination shall be performed to meet the specified requirements.

1.1 This specification covers the chemical, mechanical, and metallurgical requirements for cast titanium-6aluminum-4vanadium alloy (UNS R56406).

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
