Historical (view previous versions of standard)
This specification covers the requirements for stainless steel forgings for surgical implants. Materials for forgings shall be bars or wire and shall be forged by hammering, pressing, rolling, extruding, or upsetting. The material shall comply with the manufacturing procedure, chemical composition, mechanical requirements, and test methods indicated in this specification. Mechanical testing includes tension, tensile, elongation, and hardness tests. Special tests shall also be done such as corrosion tests, grain size, and fluorescent penetrant inspection.
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.
1.1 This specification covers the requirements of forged stainless steel for surgical implants when the material forged conforms to Specifications F138 (UNS S31673), F1314 (UNS S21910), F1586 (UNS S31675), F2229 (UNS S29108), or F2581 (UNS R56320).
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.
