Scope

1.1 This specification covers the material requirements of cobalt-28chromium-6molybdenum alloy high-strength forgings for the manufacture of surgical implants. Material conforming to this specification has been evaluated for biocompatibility and corrosion resistance and has been found to be comparable to material conforming to Specification F 75. The properties specified in this document specifically apply to finished or semifinished parts that receive no subsequent metallurgical processing.

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of the inch-pound units may be approximate.

1.3 Wrought material to be used as forging stock in the manufacture of forgings conforming to this specification, typically hot worked and unannealed with a surface finish suitable for forging, shall be fabricated and supplied in accordance with F 1537.
