3、l wall and minimumwall seamless ferritic alloy-steel pipe intended for high-temperature service.Pipe ordered to this specification shall besuitable for bending,flanging(vanstoning),and similar form-ing operations,and for fusion welding.Selection will dependupon design,service conditions,mechanical p
4、roperties,andhigh-temperature characteristics.1.2 Several grades of ferritic steels(see Note 1)are covered.Their compositions are given in Table 1.NOTE1Ferritic steels in this specification are defined as low-andintermediate-alloy steels containing up to and including 10%chromium.1.3 Supplementary r
5、equirements(S1 to S8)of an optionalnature are provided.Supplementary requirements S1 throughS6 call for additional tests to be made,and when desired,shallbe so stated in the order together with the number of such testsrequired.1.4 The values stated in either SI units or inch-pound unitsare to be reg
6、arded 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
7、 units shall apply unless the“M”designation of this specification is specified in the order.NOTE2The dimensionless designator NPS(nominal pipe size)hasbeen substituted in this standard for such traditional terms as“nominaldiameter,”“size,”and“nominal size.”2.Referenced Documents2.1 ASTM Standards:3A
