Designation:A572/A572M15American Association StateHighway and TransportationOfficals StandardAASHTO No.:M223Standard Specification forHigh-Strength Low-Alloy Columbium-Vanadium StructuralSteel1This standard is issued under the fixed designation A572/A572M;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 five grades of high-strengthlow-alloy structural steel shapes,plates,sheet piling,and bars.Grades 42 290,50 345,and 55 380 are intended forriveted,bolted,or welded structures.Grades 60 415 and 65450 are intended for riveted or bolted construction of bridges,or for riveted,bolted,or welded construction in other applica-tions.1.2 For applications,such as welded bridge construction,where notch toughness is important,notch toughness require-ments are to be negotiated between the purchaser and theproducer.1.3 Specification A588/A588M shall not be substituted forSpecification A572/A572M without agreement between thepurchaser and the supplier.1.4 The use of columbium,vanadium,titanium,nitrogen,orcombinations thereof,within the limitations noted in Section 5,is required;the selection of type(1,2,3,or 5)is at the optionof the producer,unless otherwise specified by the purchaser.(See Supplementary Requirement S90.)1.5 The maximum thicknesses available in the grades andproducts covered by this specification are shown in Table 1.1.6 When the steel is to be welded,a welding proceduresuitable for the grade of steel and intended use or service is tobe utilized.See Appendix X3 of Specification A6/A6M forinformation on weldability.1.7 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 are not exact equivalents;therefore,each system is tobe used independently of the other,without combining valuesin any way.1.8 The text of this specification contains notes or footnotes,or both,that provide explanatory material.Such notes andfootnotes,excluding those in tables and figures,do not containany mandatory requirements.1.9 For structural products produced from coil and fur-nished without heat treatment or with stress relieving only,theadditional requirements,including additional testing require-ments and the reporting of additional tests,of A6/A6M apply.2.Referenced Documents2.1 ASTM Standards:2A6/A6M Specification for General Requirements for RolledStructural Steel Bars,Plates,Shapes,and Sheet PilingA36/A36M Specification for Carbon Structural SteelA514/A514M SpecificationforHigh-Yield-Strength,Quenched and Tempered Alloy Steel Plate,Suitable forWeldingA588/A588M Specification for High-Strength Low-AlloyStructural Steel,up to 50 ksi 345 MPa Minimum YieldPoint,with Atmospheric Corrosion Resistance3.General Requirements for Delivery3.1 Structural products furnished under this specificationshall conform to the requirements of the current edition ofSpecification A6/A6M,for the specific structural productordered,unless a conflict exists in which case this specificationshall prevail.3.2 Coils are excluded from qualification to this specifica-tion until they are processed into a finished structural product.Structural products produced from coil means structural prod-ucts that have been cut to individual lengths from a coil.The1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.02 on Structural Steel for Bridges,Buildings,Rolling Stock and Ships.Current edition approved March 1,2015.Published March 2015.Originallyapproved in 1966.Last previous edition approved in 2013 as A572/A572M 13a.DOI:10.1520/A0572_A0572M-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 processor directly controls,or is responsible for,the operationsinvolved in the processing of a coil into a finished structuralproduct.Such operations include decoiling,leveling orstraightening,hot-forming or cold-forming(if applicable),cutting to length,testing,inspection,conditioning,heat treat-ment(if applicable),packaging,marking,loading for shipment,and certification.NOTE1For structural products produced from coil and furnishedwithout heat treatment or with stress relieving only,two test results are tobe reported for each qualify
