ASTM A249 - A 249M - 15a.pdf

Designation A249/A249M − 15a Used in USDOE-NE StandardsStandard Specification forWelded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes1This standard is issued under the fixed designation A249/A249M; 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 nominal-wall-thicknesswelded tubes and heavily cold worked welded tubes made fromthe austenitic steels listed in Table 1, with various gradesintended for such use as boiler, superheater, heat exchanger, orcondenser tubes.1.2 Grades TP304H, TP309H, TP309HCb, TP310H,TP310HCb, TP316H, TP321H, TP347H, and TP348H aremodifications of Grades TP304, TP309S, TP309Cb, TP310S,TP310Cb, TP316, TP321, TP347, and TP348, and are intendedfor high-temperature service such as for superheaters andreheaters.1.3 The tubing sizes and thicknesses usually furnished tothis specification are1⁄8 in. [3.2 mm] in inside diameter to 12 in.[304.8 mm] in outside diameter and 0.015 to 0.320 in. [0.4 to8.1 mm], inclusive, in wall thickness. Tubing having otherdimensions may be furnished, provided such tubes complywith all other requirements of this specification.1.4 Mechanical property requirements do not apply totubing smaller than1⁄8 in. [3.2 mm] in inside diameter or 0.015in. [0.4 mm] in thickness.1.5 Optional supplementary requirements are provided and,when one or more of these are desired, each shall be so statedin the order.1.6 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.1.7 The following safety hazards caveat pertains only to thetest method described in the Supplementary Requirements ofthis specification. This standard does not purport to address allof the safety 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. A specific warningstatement is given in Supplementary Requirement S7, NoteS7.1.2.

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 following3.1.1 Quantity feet, metres, or number of lengths,3.1.2 Name of material welded tubes WLD or heavily coldworked tubes HCW,3.1.3 Grade Table 1,3.1.4 Size outside diameter and nominal wall thickness,3.1.5 Length specific or random,3.1.6 Optional requirements 13.6,3.1.7 Test report required see Certification Section ofSpecification A1016/A1016M,3.1.8 Specification designation, and3.1.9 Special requirements and any supplementary require-ments selected.4. General Requirements4.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A1016/A1016M, unless otherwise providedherein.5. Manufacture5.1 The welded WLD tubes shall be made from flat-rolledsteel by an automatic welding process with no addition of fillermetal.5.1.1 Subsequent to welding and prior to final heattreatment, the tubes shall be cold worked either in both weldand base metal or in weld metal only. The method of coldworking may be specified by the purchaser. When cold drawn,the purchaser may specify the minimum amount of reduction incross-sectional area or wall thickness, or both.5.1.2 Heavily cold worked HCW tubes shall be made byapplying cold working of not less than 35 reduction in bothwall and weld to a welded tube prior to the final anneal. Nofiller metal shall be used in the making of the weld. Prior tocold working, the weld shall be 100 radiographically in-spected in accordance with the requirements of ASME Boilerand Pressure Vessel Code, Section VIII, Division 1, latestrevision, Paragraph UW 51.6. Heat Treatment6.1 All material shall be furnished in the heat-treatedcondition in accordance with the requirements of Table 2.6.2 A solution annealing temperature above 1950 F [1065C] may impair the resistance to intergranular corrosion aftersubsequent exposure to sensitizing conditions in TP309HCb,TP310HCb, TP321, TP321H, TP347, TP347H, TP348, andTP348H. When specified by the purchaser, a lower temperaturestabilization or re-solution anneal shall be used subsequent tothe initial high temperature solution anneal see SupplementaryRequirement S4.6.3 N08020 shall be supplied in the stabilization treatmentcondition.7. Chemical Composition7.1 The heat analysis shall conform to the requirements asto chemical composition given in Table 1.8. Product Analysis8.1 An analysis of either one length of flat-rolled stock orone tube shall be made for each heat. The chemical composi-tion thus determined shall conform to the requirements given inSection 7.8.2 A product analysis tolerance of Table A1.1 in Specifi-cation A480/A480M shall apply. The product analysis toler-ance is not applicable to the carbon content for material with aspecified maximum carbon of 0.04 or less.8.3 If the original test for product analysis fails, retests oftwo additional lengths of flat-rolled stock or tubes shall bemade. Both retests for the elements in question shall meet therequirements of the specification; otherwise all remainingmaterial in the heat or lot See Note 1 shall be rejected or, atthe option of the producer, each length of flat-rolled stock ortube may be individually tested for acceptance. Lengths offlat-rolled stock or tubes that do not meet the requirements ofthe specification shall be rejected.NOTE 1For flattening and flange requirements, the term lot applies toall tubes prior to cutting of the same nominal size and wall thicknesswhich are produced from the same heat of steel. When final heat treatmentis in a batch-type furnace, a lot shall include only those tubes of the samesize and from the same heat which are heat treated in the same furnacecharge. When the final heat treatment is in a continuous furnace, thenumber of tubes of the same size and from the same heat in a lot shall bedetermined from the size of the tubes as prescribed in Table 3.NOTE 2For tension and hardness test requirements, the term lotapplies to all tubes prior to cutting, of the same nominal diameter and wallthickness which are produced from the same heat of steel. When final heattreatment is in a batch-type furnace, a lot shall include only those tubes ofthe same size and the same heat which are heat treated in the same furnacecharge. When the final heat treatment is in a continuous furnace, a lot shallinclude all tubes of the same size and heat, annealed in the same furnaceat the same temperature, time at heat, and furnac
