2、 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.
3、 Department of Defense.1. Scope*1.1 This specification2 covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from theaustenitic steels listed in Table 1, with various grades intended for such use as boiler, superheater, heat exchanger, or condensertubes.1.2 Grades TP3
4、04H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H are modificationsof Grades TP304, TP309S, TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, and TP348, and are intended for high-temperature service such as for superheaters and reheaters.1.3 The tubing sizes and thicknesses us
5、ually furnished to this specification are 18 in. 3.2 mm in inside diameter to 12 in. 304.8mm in outside diameter and 0.015 to 0.320 in. 0.4 to 8.1 mm, inclusive, in wall thickness. Tubing having other dimensions maybe furnished, provided such tubes comply with all other requirements of this specific
6、ation.1.4 Mechanical property requirements do not apply to tubing smaller than 18 in. 3.2 mm in inside diameter or 0.015 in. 0.4mm in thickness.1.5 Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated inthe order.1.6 The values stated i
7、n either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems ma
8、y result in non-conformance with the standard. Theinch-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 the test method described in the Supplementary Requirements of thisspecification. This st
9、andard does not purport to address all of the safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.

Ordering Information3.1 It is the responsibility
37、of the purchaser to specify all requirements that are necessary for material ordered under thisspecification. Such requirements may include, but are not limited to, the following:3.1.1 Quantity (feet, metres, or number of lengths),3.1.2 Name of material welded tubes (WLD) or heavily cold worked tube
38、s (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 of Specification A1016/A1016M),3.1.8 Specification designation, and3.1.9 Special requireme
39、nts and any supplementary requirements selected.4. General Requirements4.1 Material furnished under this specification shall conform to the applicable requirements of the current edition ofSpecification A1016/A1016M, unless otherwise provided herein.5. Manufacture5.1 The welded (WLD) tubes shall be
40、made from flat-rolled steel by an automatic welding process with no addition of fillermetal.5.1.1 Subsequent to welding and prior to final heat treatment, the tubes shall be cold worked either in both weld and base metalor in weld metal only.The method of cold working may be specified by the purchas
41、er.When cold drawn, the purchaser may specifythe minimum amount of reduction in cross-sectional area or wall thickness, or both.5.1.2 Heavily cold worked (HCW) tubes shall be made by applying cold working of not less than 35 % reduction in both walland weld to a welded tube prior to the final anneal
42、. No filler metal shall be used in the making of the weld. Prior to cold working,the weld shall be 100 % radiographically inspected in accordance with the requirements ofASME Boiler and PressureVessel Code,Section VIII, Division 1, latest revision, Paragraph UW 51.6. Heat Treatment6.1 All material s
43、hall be furnished in the heat-treated condition in accordance with the requirements of Table 2.6.2 A solution annealing temperature above 1950 F 1065 C may impair the resistance to intergranular corrosion aftersubsequent exposure to sensitizing conditions in TP309HCb, TP310HCb, TP321, TP321H, TP347,
44、 TP347H, TP348, and TP348H.When specified by the purchaser, a lower temperature stabilization or re-solution anneal shall be used subsequent to the initial hightemperature solution anneal (see Supplementary Requirement S4).7. Chemical Composition7.1 The heat analysis shall conform to the requirement
45、s as to chemical composition given in Table 1.8. Product Analysis8.1 An analysis of either one length of flat-rolled stock or one tube shall be made for each heat. The chemical composition thusdetermined shall conform to the requirements given in Section 7.8.2 A product analysis tolerance of Table A
46、1.1 in Specification A480/A480M shall apply. The product analysis tolerance is notapplicable to the carbon content for material with a specified maximum carbon of 0.04 % or less.8.3 If the original test for product analysis fails, retests of two additional lengths of flat-rolled stock or tubes shall
47、 be made. Bothretests for the elements in question shall meet the requirements of the specification; otherwise all remaining material in the heator lot (See Note 1) shall be rejected or, at the option of the producer, each length of flat-rolled stock or tube may be individuallytested for acceptance.
48、 Lengths of flat-rolled stock or tubes that do not meet the requirements of the specification shall be rejected.NOTE 1For flattening and flange requirements, the term lot applies to all tubes prior to cutting of the same nominal size and wall thickness which4 Available from American Society of Mecha
