Designation:B464/B464M15Standard Specification forWelded UNS N08020 Alloy Pipe1This standard is issued under the fixed designation B464/B464M;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.Scope*1.1 This specification2covers welded UNS N08020 alloypipe for general corrosion-resisting and low-or high-temperature service.1.2 The pipe covered is nominal pipe sizes up to andincluding NPS 6 168 mm with the nominal wall thicknessesgiven as Schedules 5S,10S,and 40S and nominal pipe sizes upto and including NPS 2 60 mm also including Schedule 80S.Table 2 of Specification B775 is based on Table A1 of ANSIB36.19 and gives the nominal dimensions of these sizes.Table 3 of Specification B775 lists the dimensional require-ments of these sizes.Pipe having other dimensions may befurnished provided such pipe complies with all other require-ments of this specification.1.3 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.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to become familiarwith all hazards including those identified in the appropriateSafety Data Sheet(SDS)for this product/material as providedby the manufacturer,to establish appropriate safety and healthpractices,and determine the applicability of regulatory limi-tations prior to use.2.Referenced Documents2.1 ASTM Standards:3A262 Practices for Detecting Susceptibility to IntergranularAttack in Austenitic Stainless SteelsB775 Specification for General Requirements for Nickel andNickel Alloy Welded PipeB899 Terminology Relating to Non-ferrous Metals and Al-loys2.2 ANSI Standard:B36.19 Stainless Steel Pipe43.Terminology3.1 DefinitionsDefinitions for terms defined in Terminol-ogy B899 shall apply unless otherwise defined by the require-ments of this document.4.General Requirement4.1 Material furnished in accordance with this specificationshall conform to the applicable requirements of the currentedition of Specification B775 unless otherwise providedherein.5.Ordering Information5.1 It is the responsibility of the purchaser to specify allrequirements that are necessary for material ordered under thisspecification.Examples of such requirements include,but arenot limited to,the following:5.1.1 Quantity(feet or number of lengths),5.1.2 UNS number,5.1.3 Size(nominal pipe size and schedule),5.1.4 Length(random or specific),5.1.5 ASTM designation,5.1.6 Product AnalysisState if required,5.1.7 CertificationState if a certification or a report of testresults is required,5.1.8 Purchaser InspectionState which tests or inspec-tions are to be witnessed,if any,and5.1.9 Supplementary requirements,if any.6.Materials and Manufacture6.1 The pipe shall be made from flat-rolled stock by anautomatic welding process with no addition of filler metal.1This specification is under the jurisdiction of ASTM Committee B02 onNonferrous Metals and Alloys and is the direct responsibility of SubcommitteeB02.07 on Refined Nickel and Cobalt and Their Alloys.Current edition approved Oct.1,2015.Published November 2015.Originallyapproved in 1967.Last previous edition approved in 2010 as B464 10.DOI:10.1520/B0464_B464M-15.2For ASME Boiler and Pressure Vessel Code applications,see related Specifi-cation SB-464 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*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 6.2 Heat TreatmentPipe of UNS N08020 alloy shall befurnished in the stabilized-annealed condition.NOTE1The recommended annealing temperatures are 1800 to 1850F982 to 1010C for UNS N08020.7.Chemical Composition7.1 The material shall conform to the composition limitsspecified in Table 1.One test is required for each lot as definedin Specification B775.7.2 If a product analysis is performed,it shall meet thechemistry limits prescribed in Table 1,subject to the analysistolerances specified in Specification B775.8.Mechanical Properties and Other Requirements8.1 Mechanical PropertiesThe material shall conform tothe mechanical property requirements specified in
