| Summary: | This specification covers the requirements for unfinished cobalt-28chromium-6molybdenum (UNS R30075) investment product alloy castings for surgical implant applications, and casting alloys of the same in the form of shot, bar, or ingots to be used in the manufacture of surgical implants. This specification does not apply to completed surgical implants made from castings. Both product castings and casting alloys shall conform to specified chemical composition and mechanical requirements including ultimate tensile strength, yield strength, elongation, and reduction of area. Product castings shall additional undergo liquid penetrant, radiographic, metallographic, and hardness examination. |
| Keywords: | castings—surgical; cobalt alloys; cobalt alloys (for surgical implants); cobalt-chromium-molybdenum-metals (for surgical implants); |
| Scope: | 1.1 This specification covers the chemical, mechanical, and metallurgical requirements for cobalt-28 chromium-6 molybdenum alloy unfinished investment product castings for surgical implant applications and casting alloy in the form of shot, bar, or ingots to be used in the manufacture of surgical implants. This specification does not apply to completed surgical implants made from castings. 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 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. |
