3、se.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 spec

5、ification 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 r

6、equirements 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 un

7、itsare 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 thes

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 allo

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 applic

43、able 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 speci

44、fication; 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

45、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 th
