Designation:A1103/A1103M16Standard Specification forSeamless Cold-Finished Carbon Steel Structural FrameTubing for Automotive Racing Applications1This standard is issued under the fixed designation A1103/A1103M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification is for seamless cold-finished carbonsteel round structural frame tubing for automotive racingapplications.The chemical requirements are listed in Table 1.Tubing may be used for other applications requiring similartolerances and properties.The specification includes require-ments for heat treatment and mechanical properties to meet theneeds for the application.The tubing is intended to be bent andjoined by welding.The welding procedure shall be suitable forthe grade,the condition of the components,and the intendedservice.1.2 The tubing outside diameter size range is from 0.625 to2.0 in.16 to 50 mm.The wall thickness shall be specified asa minimum wall.1.3 Optional supplementary requirements may be providedand,when one or more of these are desired,each shall be sostated in the order.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 may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in non-conformance with thestandard.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.1.5 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 establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A450/A450M Specification for General Requirements forCarbon and Low Alloy Steel TubesA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel Products3.Ordering Information3.1 Orders for material under this specification shouldinclude the following,as required,to describe the desiredmaterial adequately:3.1.1 Specification designation,3.1.2 Name of material(seamless structural frame tubing),3.1.3 Quantity(feet,weight,or number of pieces),3.1.4 Dimensions(outside diameters and wall thickness,(Section 11),3.1.5 Length(specific or random,mill lengths,(Section11),3.1.6 Product analysis(Section 8,if required),3.1.7 Special mechanical tests(flare or flatten,Section 10,ifrequired),3.1.8 Surface finish(as-cold finished stress relieved,orground outside surface,if required),3.1.9 Individual supplementary requirements,if required,3.1.10 Packaging,3.1.11 Special marking(Section 16),and3.1.12 Special packing(Section 17).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.Materials and Manufacture5.1 The steel may be made by any process.1This 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 Dec.1,2016.Published December 2016.DOI:10.1520/A1103_A1103M-16.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 If a specific type of melting is required by the purchaser,it shall be as stated on the purchase order.5.3 The primary melting may incorporate separate degas-sing or refining,and may be followed by secondary melting,such as electroslag or vacuum-arc remelting.If secondarymelting is employed,the heat shall be defined as all of theingots remelted from a single primary heat.5.4 Steel may be cast in ingots or may be strand cast.Whensteel of different grades is sequentially strand cast,identifica-tion of the resultant transition material is required.Theproducer shall remove the transition material by an establishedprocedure that positively separates the grades.5.5 Tubes shall be made by a seamless process and shall becold finished.5.5.1 Seamless tubing is a tubular product made without awelded seam.It is manufactured usually by hot working steeland,if necessary,by subsequently cold finishing the hot-worked tubular product to produce the desired shape,dimensions,and properties.5.6 The tubing shall be supplied in the cold finishedcond
