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.

1.1 This specification covers the requirements for alpha plus beta titanium alloy forgings for surgical implants when the material forged conforms to Specifications F 136 (UNS R56401), F 1295 (UNS R56700), or F 1472 (UNS R56400).

1.2 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents in parentheses are for information only.
