Designation:A210/A210M02(Reapproved 2012)Standard Specification forSeamless Medium-Carbon Steel Boiler and SuperheaterTubes1This standard is issued under the fixed designation A210/A210M;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 minimum-wall-thickness,seamless medium-carbon steel,boiler tubes and boiler flues,including safe ends(see Note 1),arch and stay tubes,andsuperheater tubes.NOTE1This type is not suitable for safe ending by forge welding.1.2 The tubing sizes and thicknesses usually furnished tothis specification are12in.to 5 in.12.7 to 127 mm in outsidediameter and 0.035 to 0.500 in.0.9 to 12.7 mm,inclusive,inminimum wall thickness.Tubing having other dimensions maybe furnished,provided such tubes comply with all otherrequirements of this specification.1.3 Mechanical property requirements do not apply totubing smaller than18in.3.2 mm in inside diameter or 0.015in.0.4 mm in thickness.1.4 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.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.2.Referenced Documents2.1 ASTM Standards:3A450/A450M Specification for General Requirements forCarbon and Low Alloy Steel Tubes3.Ordering Information3.1 Orders for material under this specification shouldinclude the following,as required,to describe the desiredmaterial adequately:3.1.1 Quantity(feet,metres,or number of lengths),3.1.2 Name of material(seamless tubes),3.1.3 Grade,3.1.4 Manufacture(hot-finished or cold-finished),3.1.5 Size(outside diameter and minimum wall thickness),3.1.6 Length(specific or random),3.1.7 Optional requirements(Sections 7 and 10),3.1.8 Test report required,(see Certification Section ofSpecification A450/A450M),3.1.9 Specification designation,and3.1.10 Special requirements.4.General Requirements4.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A450/A450M,unless otherwise provided herein.5.Manufacture5.1 Steelmaking PracticeThe steel shall be killed.5.2 The tubes shall be made by the seamless process andshall be either hot-finished or cold-finished,as specified.6.Heat Treatment6.1 Hot-finished tubes need not be heat treated.Cold-finished tubes shall be given a subcritical anneal,a full anneal,or a normalizing heat treatment after the final cold finishingprocess.7.Surface Condition7.1 If pickling or shot blasting or both are required,thisshall be specifically stated in the order.8.Chemical Composition8.1 The steel shall conform to the requirements as tochemical composition prescribed in Table 1.8.2 When a grade is ordered under this specification,sup-plying an alloy grade that specifically requires the addition of1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.09 on Carbon Steel Tubular Products.Current edition approved Sept.1,2012.Published November 2012.Originallyapproved in 1938.Last previous edition approved in 2007 as A210/A210M 02(2007).DOI:10.1520/A0210_A0210M-02R12.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-210 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);any element other than those listed for the ordered grade inTable 1 is not permitted.9.Product Analysis9.1 When requested on the purchase order,a product analy-sis shall be made by the supplier from one tube or billet perheat.The chemical composition thus determined shall conformto the requirements specified.9.2 If the original test for product analysis fails,retests oftwo additional billets or tubes shall be made.Both retests forthe elements in question shall meet the requirements of thespecification;otherwise,all remaining material in the heat orlot(see Note 2)shall be rejected or,at the option of theproducer,each billet or tube may be individually tested foracceptance.Billets or tubes which do not meet the require-ments of the specification shall be rejected.NOTE2For flattening and flaring requi
