ASTM A451/A451M-02

Standard Specification for Centrifugally Cast Austenitic Steel Pipe for High-Temperature Service

SCOPE
1.1 This specification covers austenitic alloy steel pipe for use in high-temperature, corrosive, or nuclear pressure service.
1.2 Several grades of austenitic stainless steel are covered as indicated in Table 1.
1.3 Optional supplementary requirements are provided when additional testing may be required.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exactly equivalents; therefore, each system must be used independently of each other. Combining values from the two systems may result in nonconformance with the specification.
Note 1—This specification is not intended to cover centrifugal pipe made from alloys containing more than 0.20 % carbon, such as are covered by Specification A 297.
