Full Description

1.1This specification2 covers austenitic alloy steel pipe for use in high-temperature, corrosive, or nuclear pressure service.

1.2Several grades of austenitic stainless steel are covered as indicated in Table 1.

1.3Optional supplementary requirements are provided when additional testing may be required.

1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

1.4.1Within the text, the SI units are shown in brackets.

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 A297/A297M.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
