This standard is issued under the fixed designation A 335/A 335M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon ( ュ) indicates an editorial change since the last revision or reapproval.

1.Scope
1.1This specification covers nominal (average) wall seamless alloy-steel pipe intended for high-temperature service (Mote 1). Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.

NOTE 1 Α Appendix X1 lists the sizes and wall thicknesses of pipe which may be obtained under current commercial practice.

1.2 Several grades of ferritic steels (Note 2) are covered. Their compositions are given in Table 1.
Note 2
ΑFerritic steels in this specification are defined as low and intermediate-alloy steels containing up to and including 10% chromium.
1.3 Supplementary requirements (S1 to S7) of an optional nature are provided. These supplementary requirements call for additional tests to be made, and when desired, shall be so stated in the order together with the number of such tests 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 exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.

Note 3ΑThe dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size," and "nominal size."
