ABSTRACT 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. SCOPE 1.1 This specification covers the chemical, mechanical, and metallurgical requirements for cast titanium-6aluminum-4vanadium alloy (UNS R56406). 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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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.
