Designation:B43214Standard Specification forCopper and Copper Alloy Clad Steel Plate1This standard is issued under the fixed designation B432;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification establishes the requirements for plateof a carbon steel or low-alloy steel base to which is integrallyand continuously bonded on one or both sides a layer of copperor copper-base alloy.The material is generally intended forpressure vessel use but may be used in other structuralapplications where corrosion resistance or conductivity of thealloy is of prime importance.1.2 UnitsThe values stated in inch-pound units are to beregarded as standard.The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.2.Referenced Documents2.1 ASTM Standards:2A6/A6M Specification for General Requirements for RolledStructural Steel Bars,Plates,Shapes,and Sheet PilingA20/A20M Specification for General Requirements for SteelPlates for Pressure VesselsA578/A578M Specification for Straight-Beam UltrasonicExamination of Rolled Steel Plates for Special Applica-tionsB96/B96M Specification for Copper-Silicon Alloy Plate,Sheet,Strip,and Rolled Bar for General Purposes andPressure VesselsB152/B152M Specification for Copper Sheet,Strip,Plate,and Rolled BarB171/B171M Specification for Copper-Alloy Plate andSheet for Pressure Vessels,Condensers,and Heat Ex-changersB846 Terminology for Copper and Copper AlloysE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications2.2 ASME Code:3Boiler and Pressure Vessel Code,Section VIIIBoiler and Pressure Vessel Code,Section IX3.Terminology3.1 For definitions of terms related to copper and copperalloys,refer to Terminology B846.3.2 Definitions of Terms Specific to This Standard:3.2.1 base metal(backing steel),ncomponent to whichthe cladding metal is applied,usually the greater percentage ofthe composite plate and usually consisting of carbon orlow-alloy steel.3.2.2 blind flange,nsame as a cover.3.2.3 bonding,nadhesion of one surface to another with-out the use of an adhesive as a bonding agent.3.2.4 cladding metal,nthe copper or copper-base alloycomponent of the composite plate.3.2.5 cover,na component with similar features to atubesheet which is used as a closure and which typicallyrequires surface machining over part of the face while main-taining minimum specified minimum thickness.3.2.6 double-clad,nmaterial is considered as double-cladwhen both sides of the steel base metal are covered with coppercladding.3.2.7 interface,nof the clad product,is that region of thethickness in which the product transitions from essentially100%base metal to 100%cladding metal,also referred to asthe bond or bondzone.3.2.8 integrally and continuously bonded,adva conditionin which the cladding metal and base metal are broughttogether to form a metallurgical bond at essentially the entireinterface of the two metals by means other than those processesthat do not produce a homogeneous composite plate.3.2.9 plate,nthe term plate as used in this specificationapplies to material 0.188 in.(4.78 mm)and over in thickness,and over 10 in.(254 mm)in width.1This specification is under the jurisdiction ofASTM Committee B05 on Copperand CopperAlloys and is the direct responsibility of Subcommittee B05.01 on Plate,Sheet,and Strip.Current edition approved Sept.1,2014.Published November 2014.Originallyapproved in 1966.Last previous edition approved in 2009 as B432 09a.DOI:10.1520/B0432-14.2For 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.3Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.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 3.2.10 single-clad,nmaterial is considered as single-cladwhen only one side of the steel base metal is covered withcopper cladding.3.2.11 tubesheet,nthe term tubesheet as used in thisspecification applies to a clad plate,which is used in a heatexchanger to separate the tubeside and shell side components.Typically,but not necessarily,tubesheets are round,relativelythick,and require that the cladding and/or base be machinedflat over part or all of the face while maintaining specifiedminimum thicknesses.4.Ordering Information4.1 Include the following specified choices when placingorders for product under this specification,as appl
