3、nse.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,
4、 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 spe
5、cification are18 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
6、requirements do not apply totubing smaller than18 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 u
7、nitsare 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 the
8、standard. 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 all
9、of 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.

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
43、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
44、 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 specific
45、ation 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

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 ten
