Designation:A565/A565M10(Reapproved 2017)1Standard Specification forMartensitic Stainless Steel Bars for High-TemperatureService1This standard is issued under the fixed designation A565/A565M;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.1NOTERevised Table 1 editorially to show commonly accepted element name Niobium(formerly Columbium)inMarch 2017.1.Scope1.1 This specification covers hot-finished and cold-finishedmartensitic chromium steel bars for high-temperature service.The mechanical properties are developed by suitable heattreatment,as indicated for each alloy.1.2 Where strength at temperature is a factor,these steelsare generally limited to a maximum service temperature of1200F 650C.For oxidation(scaling)resistance and at lowstresses,these steels are useful to 1450F 790C.1.3 This specification is expressed in both inch-pound unitsand SI units;however,unless the purchase order or contractspecifies the applicable M specification designation(SI units),the inch-pound units shall apply.The values stated in eitherinch-pound units or SI units are to be regarded separately asstandard.Within the text,the SI units are shown in brackets.The values stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in noncon-formance with the specification.2.Referenced Documents2.1 ASTM Standards:2A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA484/A484M Specification for General Requirements forStainless Steel Bars,Billets,and ForgingsA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsA994 Guide for Editorial Procedures and Form of ProductSpecifications for Steel,Stainless Steel,and RelatedAlloysE112 Test Methods for Determining Average Grain SizeE292 Test Methods for Conducting Time-for-Rupture NotchTension Tests of MaterialsE527 Practice for Numbering Metals and Alloys in theUnified Numbering System(UNS)E562 Test Method for Determining Volume Fraction bySystematic Manual Point Count2.2 SAE Document:3SAE J1086 Recommended Practice for Numbering Metalsand Alloys(UNS)3.Ordering Information3.1 It is the responsibility of the purchaser to specify allrequirements that are necessary for material ordered under thisspecification.Such requirements may include,but are notlimited to,the following:3.1.1 Quantity(weight or number of pieces);3.1.2 Name of material(martensitic stainless steel);3.1.3 Form(bar,and so forth);3.1.4 Condition;3.1.5 Finish;3.1.6 Size,or applicable dimension including diameter,thickness,width,length,and so forth;3.1.7 Grade designation(Table 1);and3.1.8 ASTM designation number and date of issue.4.General Requirements4.1 Product furnished to this specification shall conform tothe requirements of Specification A484/A484M,including anysupplementary requirements indicated in the purchase order.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloysand is the direct responsibility of SubcommitteeA01.17 on Flat-Rolled and Wrought Stainless Steel.Current edition approved March 15,2017.Published March 2017.Originallyapproved in 1966.Last previous edition approved in 2010 as A565 10.DOI:10.1520/A0565_A0565M-10R17E01.2For 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.3Available from Society of Automotive Engineers(SAE),400 CommonwealthDr.,Warrendale,PA 15096-0001,http:/www.sae.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 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 Failure to comply with the general requirements of Specifica-tion A484/A484M constitutes nonconformance with this speci-fication.In case of conflict between the requirements of thisspecification and Specification A484/A484M,this specificationshall prevail.5.Manufacture5.1 Heat Treatment:5.1.1 The product forms covered in this specification maybe furnished in one of the following conditions:5.1.1.1 Condition AAnnealed,5.1.1.2 Condition THeat treated(for machining),5.1.1.3 Condition HTHeat treated(for high-temperatureservice),or5.1.1.4 Conditi
