Designation:A706/A706M16Standard Specification forDeformed and Plain Low-Alloy Steel Bars for ConcreteReinforcement1This standard is issued under the fixed designation A706/A706M;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 GeneralThis specification covers deformed and plainlow-alloy steel bars in cut lengths and coils for concretereinforcement intended for applications where restrictive me-chanical properties and chemical composition are required forcompatibility with controlled tensile property applications or toenhance weldability.The standard sizes and dimensions ofdeformed bars and their number designations are given inTable 1.1.2 GradeBars are of two minimum yield strength levels:namely,60 000 psi 420 MPa and 80 000 psi 550 MPa,designated as Grade 60 420 and Grade 80 550,respectively.1.3 Plain bars,in sizes up to and including 212in.63.5 mmin diameter in coils or cut lengths,when ordered,shall befurnished under this specification.For ductility properties(elongation and bending),test provisions of the nearest smallernominal diameter deformed bar size shall apply.Requirementsproviding for deformations and marking shall not be appli-cable.1.4 Controlled Tensile PropertiesThis specification limitstensile properties(Table 2)to provide the desired yield/tensileproperties for controlled tensile property applications.1.5 WeldingThis specification limits chemical composi-tion(6.2)and carbon equivalent(6.4)to enhance the weldabil-ity of the material.When this steel is to be welded,a weldingprocedure suitable for the chemical composition and intendeduse or service should be used.The use of the latest edition ofAWS D1.4D1.4M is recommended.The AWS D1.4/D1.4MWelding Code describes the proper selection of the fillermetals,preheat/interpass temperatures,as well as,performanceand procedure qualification requirements.1.6 Requirements for alternate bar sizes are presented inAnnex A1.The requirements in Annex A1 only apply whenspecified by the purchaser(see 4.2.5).1.7 The text of this specification references notes andfootnotes that provide explanatory material.These notes andfootnotes,excluding those in tables,shall not be considered asrequirements of this specification.1.8 This specification is applicable for orders in eitherinch-pound units(Specification A706)or in SI units Specifi-cation A706M.1.9 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in non-conformance with thisspecification.1.10 This specification does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this specification to establishappropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A6/A6M Specification for General Requirements for RolledStructural Steel Bars,Plates,Shapes,and Sheet PilingA370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA510/A510M Specification for General Requirements forWire Rods and Coarse Round Wire,Carbon Steel,andAlloy SteelA615/A615M Specification for Deformed and Plain Carbon-Steel Bars for Concrete ReinforcementA700 Guide for Packaging,Marking,and Loading Methodsfor Steel Products for ShipmentA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel Products1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.05 on Steel Reinforcement.Current edition approved Jan.15,2016.Published March 2016.Originallyapproved in 1974.Last previous edition approved in 2015 as A706/A706M 15.DOI:10.1520/A0706_A0706M-16.2For 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.*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 E29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE290 Test Methods for Bend Testing of Material for Ductil-ity2.2 AWS Standard:3AWS D1.4D1.4M Structural Welding CodeReinforcingSteel2.3U.S.Military Standard:4MIL-STD-129 Marking for Shipment and Storage2.4 U.S.Fede
