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. Scope

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 F136 (UNS R56401), F1295 (UNS R56700), F1472 (UNS R56400), or F2066 (UNS R58150).

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 non-conformance with the standard.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
