ASTM-F2886 › Standard Specification for Metal Injection Molded Cobalt-28Chromium-6Molybdenum Components for Surgical Implant Applications
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers chemical, mechanical, and metallurgical general requirements for metal injection molded (MIM) cobalt-28chromium-6molybddenum components to be used in manufacturing surgical implants. In this specification, the MIM components covered may have been densified beyond their as-sintered density by post-sinter processing. For the chemical requirements, the components supplied in this specification must conform in accordance to the chemical requirements specified herein in Table 1. The product analysis tolerances must also conform to the product tolerances presented in Table 2. The specification also enumerates the mechanical requirements for MIM components wherein the tensile properties of the MIM must conform to the mechanical properties in Table 3. The microstructural requirements and specimen preparation shall be in accordance with Guide E3 and Practice E407.
Scope
1.1 This specification covers the chemical, mechanical, and metallurgical requirements for metal injection molded (MIM) cobalt-28chromium-6molybdenum components to be used in the manufacture of surgical implants
1.2 The MIM components covered by this specification may have been densified beyond their as-sintered density by post-sinter processing.
1.3 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.
