Designation:A285/A285M12Standard Specification forPressure Vessel Plates,Carbon Steel,Low-andIntermediate-Tensile Strength1This standard is issued under the fixed designation A285/A285M;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 Department of Defense.1.Scope*1.1 This specification2covers carbon steel plates of low-and intermediate-tensile strengths which may be made bykilled,semi-killed,capped,or rimmed steel practices at theproducers option.These plates are intended for fusion-weldedpressure vessels.1.2 Plates under this specification are available in threegrades having different strength levels as follows:GradeTensile Strength,ksi MPaA4565 310450B5070 345485C5575 3805151.3 The maximum thickness of plates under this specifica-tion,for reasons of internal soundness,is limited to a maximumthickness of 2 in.50 mm for all grades.NOTE1For killed carbon steels only refer to the following ASTMspecifications:3A 299/A 299M Pressure Vessel Plates,Carbon Steel,Manganese-Silicon.A 515/A 515M Pressure Vessel Plates,Carbon Steel,forIntermediate-and Higher-Temperature ServiceA 516/A 516M Pressure Vessel Plates,Carbon Steel,for Moderate-and Lower-Temperature Service.1.4 For plates produced from coil and furnished withoutheat treatment or with stress relieving only,the additionalrequirements,including additional testing requirements and thereporting of additional test results,of Specification A20/A20Mapply.1.5 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 mustbe used independently of the other.Combining values from thetwo systems may result in nonconformance with the specifi-cation.2.Referenced Documents2.1 ASTM Standards:3A20/A20M Specification for General Requirements for SteelPlates for Pressure Vessels3.General Requirements and Ordering Information3.1 Material supplied to this material specification shallconform to Specification A20/A20M.These requirements out-line the testing and retesting methods and procedures,permit-ted variations in dimensions,and mass,quality and repair ofdefects,marking,loading,and ordering information.3.2 In addition to the basic requirements of this specifica-tion,certain supplementary requirements are available whenadditional control,testing,or examination is required to meetend use requirements.The purchaser is referred to the listedSupplementary requirements in this specification and to thedetailed requirements in Specification A20/A20M.3.3 Coils are excluded from qualification to this specifica-tion until they are processed into finished plate.Plates pro-duced from coil means plates that have been cut to individuallengths from coil.The processor directly controls,or isresponsible for,the operations involved in the processing ofcoils into finished plates.Such operations include decoiling,leveling,cutting to length,testing,inspection,conditioning,heat treatment(if applicable),packaging,marking,loading forshipment,and certification.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.11 on Steel Plates for Boilers and Pressure Vessels.Current edition approved May 1,2012.Published June 2012.Originallyapproved in 1946.Last previous edition approved in 2007 as A285/A285M 03(2007).DOI:10.1520/A0285_A0285M-12.2For ASME Boiler and Pressure Vessel Code applications,see related Specifi-cation SA-285/SA-285M 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.*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 States1Copyright by ASTM Intl(all rights reserved);NOTE2For plates produced from coil and furnished without heattreatment or with stress relieving only,three test results are reported foreach qualifying coil.Additional requirements regarding plate producedfrom coil are described in Specification A20/A20M.3.4 If the requirements of this specification are in conflictwith the requirements of Specification A20/A20M,the require-ments of this specification shall prevail.4.Heat Treatment4.1 Plates are normally supplied in the as-rolled condition.The plates may be ordered normalized or stress relieved,orboth.5.Chemical Composition5.1 The steel shall conform to the requirements as tochemical com
