Designation:B551/B551M12(Reapproved 2017)Standard Specification forZirconium and Zirconium Alloy Strip,Sheet,and Plate1This standard is issued under the fixed designation B551/B551M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification2covers five grades of zirconium strip,sheet,and plate.1.2 Unless a single unit is used,for example corrosion massgain in mg/dm2,the values stated in either inch-pound or SIunits are to be regarded separately as standard.The valuesstated in each system are not exact equivalents;therefore eachsystem must be used independently of the other.SI valuescannot be mixed with inch-pound values.1.3 The following precautionary caveat pertains only to thetest method portions of this specification:This standard doesnot purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of thisstandard to establish appropriate safety,health,and environ-mental practices and determine the applicability of regulatorylimitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3E8/E8M Test Methods for Tension Testing of Metallic Ma-terialsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE290 Test Methods for Bend Testing of Material for Ductil-ity3.Terminology3.1 Definitions:3.1.1 annealed,ndenotes material that exhibits a recrys-tallized grain structure.3.2 Lot Definition:3.2.1 lot,na lot shall consist of a material of the same size,shape,condition,and finish produced from the same ingot orpowder blend by the same reduction schedule and the sameheat treatment parameters.Unless otherwise agreed betweenmanufacturer and purchaser,a lot shall be limited to theproduct of an 8 h period for final continuous anneal,or to asingle furnace load for final batch anneal.3.3 Forms:3.3.1 strip,na flat product,may be supplied in coil,lessthan 6 in.150 mm in width and from 0.005 in.0.13 mm to0.188 in.4.8 mm in thickness.3.3.2 sheet,na flat product 6 in.150 mm or more inwidth and from 0.005 in.0.13 mm to 0.188 in.4.8 mm inthickness.3.3.3 plate,na flat product more than 0.125 in.3.2 mmin thickness.4.Classification4.1 The strip,sheet,or plate is to be furnished in five gradesas follows:4.1.1 Grade R60700Low oxygen zirconium.4.1.2 Grade R60702Unalloyed zirconium.4.1.3 Grade R60704Zirconium-tin.4.1.4 Grade R60705Zirconium-niobium.4.1.5 Grade R60706Zirconium-niobium.5.Ordering Information5.1 Orders for material under this specification shouldinclude the following information,as applicable:5.1.1 Standard designation and year of issue,5.1.2 Quantity(weight or number of pieces),5.1.3 Lot definition for continuous anneal,if applicable(3.2.1),5.1.4 Form(3.3)and dimensions,5.1.5 Grade(4.1),5.1.6 Metallurgical condition,if not in the recrystallizedannealed condition(6.3),1This specification is under the jurisdiction of ASTM Committee B10 onReactive and Refractory Metals and Alloys and is the direct responsibility ofSubcommittee B10.02 on Zirconium and Hafnium.Current edition approved Nov.1,2017.Published November 2017.Originallyapproved in 1971.Last previous edition approved in 2012 as B551/B551M 12.DOI:10.1520/B0551_B0551M-12R17.2For ASME Boiler and Pressure Vessel Code applications,see related Specifi-cation SB-551 in Section II of that Code.3For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 5.1.7 Chemical analysis of elements not listed(7.1.4),5.1.8 Product analysis(7.1.3 and 7.3.1),5.1.9 Tensile test temperature(8.1),5.1.10 Material condition and finish(9.1 9.5),5.1.11 Workmanship and appearance(11.1 and 11.3),5.1.12 Purchaser inspection(15.1 and 15.2),5.1.13 Rejection and referee(16.2),5.1.14 Product marking,(18.1 and 18.1.1),5.1.15 Packaging and package marking(19.1),5.1.16 Additions to the specification and supplementaryrequirements,if required,
