Designation:A353/A353M09(Reapproved 2014)Standard Specification forPressure Vessel Plates,Alloy Steel,Double-Normalized andTempered 9%Nickel1This standard is issued under the fixed designation A353/A353M;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.1.Scope1.1 This specification2covers double-normalized and tem-pered 9%nickel steel plates intended particularly for weldedpressure vessels for cryogenic service.1.2 Plates produced under this specification are subject toimpact testing at 320F 195C or at such other tempera-tures as are agreed upon.1.3 The maximum thickness of plates is limited only by thecapacity of the material to meet the specific mechanicalproperty requirements;however,current mill practice normallylimits this material to 2 in.50 mm max.1.4 This material is susceptible to magnetization.Use ofmagnets in handling after heat treatment should be avoided ifresidual magnetism would be detrimental to subsequent fabri-cation or service.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 VesselsA435/A435M Specification for Straight-Beam UltrasonicExamination of Steel PlatesA577/A577M Specification for Ultrasonic Angle-Beam Ex-amination of Steel PlatesA578/A578M Specification for Straight-Beam UltrasonicExamination of Rolled Steel Plates for Special Applica-tions3.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 Inadditiontothebasicrequirementsofthisspecification,certain supplementary requirements are availablewhen additional control,testing,or examination is required tomeet end use requirements.The purchaser is referred to thelisted supplementary requirements in this specification and tothe detailed requirements in Specification A20/A20M.3.3 If the requirements of this specification are in conflictwith the requirements of Specification A20/A20M,the require-ments of this specification shall prevail.4.Manufacture4.1 Steelmaking PracticeThe steel shall be killed andshall conform to the fine austenitic grain size requirement ofSpecification A20/A20M.5.Heat Treatment5.1 All plates shall be heat treated in accordance with 5.2.Shell plates and other parts,including heads and reinforcingpads that are heated for forming shall be heat treated afterforming in accordance with 5.2.5.2 Heat Treatment Procedure:5.2.1 First Normalizing TreatmentHeat the plate to auniform temperature of 1650 6 25F 900 6 15C,hold atthat temperature for a minimum of 1 h/in.2.4 min/mm ofthickness,but in no case less than 15 min,and cool in air.5.2.2 Second Normalizing TreatmentReheat the plate to auniform temperature of 1450 6 25F 790 6 15C,hold atthat temperature for a minimum of 1 h/in.2.4 min/mm ofthickness,but in no case less than 15 min,and cool in air.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 March 1,2014.Published March 2014.Originallyapproved in 1952.Last previous edition approved in 2009 as A353/A353M 09.DOI:10.1520/A0353_A0353M-09R14.2For ASME Boiler and Pressure Vessel Code applications,see related Specifi-cation SA-353/SA-353M 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1Copyright by ASTM Intl(all rights reserved);5.2.3 Tempering TreatmentReheat the plate to a uniformtemperature within the range from 1050 to 1125F 565 to605C,hold within that temperature range for a minimum of1 h/in.2.4 min/mm of thickness,but in no case less than 15min,and cool in air or water quench at a rate not less than300F/h 165C/h.5.2.4 If hot forming is performed after heating to a tempera-ture within the range from 1650 to 1750F 900 to 955C thefirst normalizing treatment(5.2.1)may be omitted.5.2.
