Designation:A352/A352M18aStandard Specification forSteel Castings,Ferritic and Martensitic,for Pressure-Containing Parts,Suitable for Low-Temperature Service1This standard is issued under the fixed designation A352/A352M;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 specification2covers steel castings for valves,flanges,fittings,and other pressure-containing parts intendedprimarily for low-temperature service.1.2 Several grades of ferritic steels and one grade ofmartensitic steel are covered.Selection of analysis will dependon design and service conditions(Note 1).The temperatureshown is the lowest temperature at which the material ordinar-ily is required to meet the impact requirements of thisspecification(see Supplementary Requirement S51,ImpactTest Temperatures).Users should note that hardenability ofsome of the grades mentioned may restrict the maximum sizeat which the required mechanical properties are obtainable(seeAppendix X1).GradeUsual Minimum TestingTemperatures,F CLCA25 32LCB50 46LCC50 46LC175 59LC2100 73LC21100 73LC3150 101LC4175 115LC9320 196CA6NM100 73NOTE1This specification covers the low-temperature requirementsparticularly pertinent for ferritic and martensitic steels.Certain grades ofaustenitic steel castings furnished in accordance with Specification A351/A351M have been found suitable for low-temperature service down to300 F 184 C and others down to 425 F 254 C.These gradesmay be used when impact tested in accordance with SpecificationA352/A352M with energy levels and temperatures of test mutually agreedupon between the purchaser and the manufacturer.As a guide to theselection of energy levels and testing temperatures,Appendix X1 shouldbe consulted.1.3 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.Inch-pound units are applicable for material ordered toSpecification A352 and SI units for material ordered toSpecification A352M.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3A351/A351M Specification for Castings,Austenitic,forPressure-Containing PartsA488/A488M Practice for Steel Castings,Welding,Qualifi-cations of Procedures and PersonnelA703/A703M Specification for Steel Castings,GeneralRequirements,for Pressure-Containing PartsE165/E165M Practice for Liquid Penetrant Examination forGeneral IndustryE709 Guide for Magnetic Particle Testing2.2 Manufacturers Standardization Society of the Valve andFittings Industry Standard:4SP-55 Quality Standard for Steel Castings for Valves,Flanges,and Fittings and Other Piping Components(Vi-sual Method)1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.18 on Castings.Current edition approved Dec.1,2018.Published December 2018.Originallyapproved in 1952.Last previous edition approved in 2018 as A352/A352M 18.DOI:10.1520/A0352_A0352M-18A.2For ASME Boiler and Pressure Vessel Code applications,see related Specifi-cation SA-352,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.4Available from Manufacturers Standardization Society of the Valve and FittingsIndustry(MSS),127 Park St.,NE,Vienna,VA 22180-4602.*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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.General Conditions for Delivery3.1 Material furnished to this specification shall conform tothe requirements of Specification A703/A703M,including anysupplementary requirements that are indicated in the
