Designation:F62011(Reapproved 2015)Standard Specification forTitanium Alloy Forgings for Surgical Implants in the AlphaPlus Beta Condition1This standard is issued under the fixed designation F620;the number immediately following the designation indicates the year of originaladoption or,in the 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 the requirements for titaniumalloy forgings for surgical implants,in the alpha plus betacondition,when the material forged conforms to SpecificationsF136(UNS R56401),F1295(UNS R56700),F1472(UNSR56400),or F2066(UNS R58150).1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately 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:2E8/E8M Test Methods for Tension Testing of Metallic Ma-terialsE10 Test Method for Brinell Hardness of Metallic MaterialsE18 Test Methods for Rockwell Hardness of Metallic Ma-terialsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE92 Test Method for Vickers Hardness of Metallic Materials(Withdrawn 2010)3E165 Practice for Liquid Penetrant Examination for GeneralIndustryE1409 Test Method for Determination of Oxygen and Nitro-gen in Titanium and Titanium Alloys by Inert Gas FusionE1447 Test Method for Determination of Hydrogen in Tita-nium and Titanium Alloys by Inert Gas Fusion ThermalConductivity/Infrared Detection MethodE2371 Test Method for Analysis of Titanium and TitaniumAlloys by Direct Current Plasma and Inductively CoupledPlasma Atomic Emission Spectrometry(Performance-Based Test Methodology)F67 Specification for Unalloyed Titanium,for Surgical Im-plant Applications(UNS R50250,UNS R50400,UNSR50550,UNS R50700)F136 Specification for Wrought Titanium-6Aluminum-4Vanadium ELI(Extra Low Interstitial)Alloy for SurgicalImplant Applications(UNS R56401)F601 Practice for Fluorescent Penetrant Inspection of Me-tallic Surgical ImplantsF1295 Specification for Wrought Titanium-6Aluminum-7Niobium Alloy for Surgical Implant Applications(UNSR56700)F1472 Specification for Wrought Titanium-6Aluminum-4Vanadium Alloy for Surgical Implant Applications(UNSR56400)F2066 Specification for Wrought Titanium-15 MolybdenumAlloy for Surgical Implant Applications(UNS R58150)SI 10 American National Standard for the Use of theInternational System of Units(SI):The Modern MetricSystem2.2 ISO Standard:ISO 9001 Quality Management Systems43.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 lotthe total number of forgings produced from thesame heat under the same conditions and heat treated atessentially the same time.4.Ordering Information4.1 Inquiries and orders for forgings under this specificationshall include the following information:4.1.1 Quantity,number of pieces,4.1.2 ASTM designation and date of issue,material grade,4.1.3 Condition,4.1.4 Mechanical properties,1This specification is under the jurisdiction of ASTM Committee F04 onMedical and Surgical Materials and Devicesand is the direct responsibility ofSubcommittee F04.12 on Metallurgical Materials.Current edition approved Dec.1,2015.Published December 2015.Originallyapproved in 1979.Last previous edition approved in 2011 as F620 11.DOI:10.1520/F0620-11R15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.1.5 Finish,4.1.6 Applicable dimensions or drawing number,4.1.7 Special tests,if any,and4.1.8 Other requirements.5.Materials and Manufacture5.1 Material for forgings shall be bars or wire fabricated inaccordance with Specification F136,F1295,F1472,or F2066.5.2 The material shall be forged by hammering,pressing,extruding,or upsetting and shall be processed,if practicable,soas to cause metal flow during the hot-working operation in thedirection most favorable for resisting stresses encountered inservice,as may be indicated to the fabricator by the purchaser.5.3 Forgings shall be free of splits,scale,cracks,flaws,andother imperfections not consistent with good commercialpractice(see Note 1).Offset or mismatch allowance,dependentupon part size and configuration,shall be within standardfo
