This specification covers alpha plus beta titanium alloy forgings for use in surgical implants such as orthopaedic medical devices. The products should be forged by hammering, pressing, extruding, or upsetting bars or wires and should be free of splits, scales, cracks, flaws, and other imperfections. After hot forging, each product should be subjected to annealing treatment consisting of heating the parts to an appropriate temperature and followed by cooling. Samples should be tested according to the specified procedure and should conform to the required values for chemical composition, tensile strength, hardness, elongation, and area reduction.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the requirements for titanium alloy forgings for surgical implants, in the alpha plus beta condition, when the material forged conforms to Specifications (UNS R56401), (UNS R56700), (UNS R56400), or (UNS R58150).
1.2 The SI units in this standard are the primary units. The values stated in either primary SI units or secondary 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.
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.
