1、Designation:F56213Standard Specification forWrought 35Cobalt-35Nickel-20Chromium-10MolybdenumAlloy for Surgical Implant Applications(UNS R30035)1This standard is issued under the fixed designation F562;the number immediately following the designation indicates the year of originaladoption or,in the
2、case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers requirements of wrought35cobalt-35nickel-20chromium-10molybdenum allo
3、y(UNSR30035)in the form of bar and wire,used for the manufactureof surgical implants.This alloy depends on combinations ofwork strengthening and aging to attain a variety of combina-tions of strength and ductility.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separat
4、ely as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.2.Referenced Documents2.1 ASTM Standards:2A751 Test Methods,Practices,and Ter
