Designation:A606/A606M15Standard Specification forSteel,Sheet and Strip,High-Strength,Low-Alloy,Hot-Rolledand Cold-Rolled,with Improved Atmospheric CorrosionResistance1This standard is issued under the fixed designation A606/A606M;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 This specification covers high-strength,low-alloy,hot-and cold-rolled sheet and strip in cut lengths or coils,intendedfor use in structural and miscellaneous purposes,where savingsin weight or added durability are important.These steels haveenhanced atmospheric corrosion resistance and are supplied intwo types:Type 2 contains 0.20%minimum copper based oncast or heat analysis(0.18%minimum Cu for product check).Type 4 contains additional alloying elements and provides alevel of corrosion resistance substantially better than that ofcarbon steels with or without copper addition(Note 1).Whenproperly exposed to the atmosphere,Type 4 steel can be usedbare(unpainted)for many applications.NOTE1For methods of establishing the atmospheric corrosion resis-tance of low-alloy steels,see Guide G101.1.2 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:2A109/A109M Specification for Steel,Strip,Carbon(0.25Maximum Percent),Cold-RolledA568/A568M Specification for Steel,Sheet,Carbon,Structural,and High-Strength,Low-Alloy,Hot-Rolled andCold-Rolled,General Requirements forA749/A749M Specification for Steel,Strip,Carbon andHigh-Strength,Low-Alloy,Hot-Rolled,General Require-ments forG101 Guide for Estimating the Atmospheric Corrosion Re-sistance of Low-Alloy Steels3.General Requirements for Delivery3.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A568/A568M and the dimensional tolerancetables of Specification A109/A109M,unless otherwise pro-vided herein.4.Ordering Information4.1 Orders for material under this specification shall includethe following information,as required,to describe adequatelythe desired material:4.1.1 ASTM specification number and date of issue,andtype,4.1.2 Name of material(high-strength low-alloy hot-rolledsheet or strip or high-strength low-alloy cold-rolled sheet orstrip),4.1.2.1 Hot rolled sheet shall either be CS or grade 50(Grade 50 shall be supplied if not specified).4.1.2.2 Cold rolled sheet shall either be CS or grade 45(Grade 45 shall be supplied if not specified).4.1.3 Condition(specify oiled or dry,as required),4.1.4 Edges(must be specified for hot-rolled sheet or strip)(see 8.1),4.1.5 FinishCold-rolled only(indicate exposed(E)orunexposed(U).Matte(dull)finish will be supplied unlessotherwise specified),and4.1.6 Dimensions(thickness,width,and whether cut lengthsor coils).NOTE2Not all producers are capable of meeting all of the limitationsof the thickness tolerance tables in Specification A568/A568M.Thepurchaser should contact the producer regarding possible limitations priorto placing an order.4.1.7 Coil size(must include inside diameter,outsidediameter,and maximum weight),1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved Nov.1,2015.Published November 2015.Originallyapproved in 1970.Last previous edition approved in 2009 as A606/A606M 09a.DOI:10.1520/A0606_A0606M-15.2For 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 4.1.8 Application(show part identification and description),4.1.9 Cast or heat(formerly ladle)analysis and mechanicalproperties report(if required)(see 10.1),and4.1.10 Special requirements(if any).4.1.10.1 When the purchaser requires thickness tolerancesfor38in.10 mm minimum edge distance(see SupplementaryRequirement in Specification A568/A568M),this requirementshall be specified in the purchase order or contract.NOTE3A typical ordering description is as follows:“ASTMA606XX,Grade 50,Type 4 high-strength low-alloy hot-rolled sheet,dry,mill edge 0.106 by 48 by 96 in.for truck frame side membe
