Designation: A249/A249M −24a Used in USDOE-NE Standards
Standard Specification for
Welded Austenitic Steel Boiler, Superheater, Heat-
Exchanger, and Condenser Tubes
1
This standard is issued under the fixed designation A249/A249M; 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 (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification
2
covers nominal-wall-thickness
welded tubes and heavily cold worked welded tubes made from
the austenitic steels listed in Table 1, with various grades
intended for such use as boiler, superheater, heat exchanger, or
condenser tubes.
1.2 Grades TP304H, TP309H, TP309HCb, TP310H,
TP310HCb, TP316H, TP321H, TP347H, and TP348H are
modifications of Grades TP304, TP309S, TP309Cb, TP310S,
TP310Cb, TP316, TP321, TP347, and TP348, and are intended
for high-temperature service such as for superheaters and
reheaters.
1.3 The tubing sizes and thicknesses usually furnished to
this specification are
1
⁄
8
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 to
8.1 mm], inclusive, in wall thickness. Tubing having other
dimensions may be furnished, provided such tubes comply
with all other requirements of this specification.
1.4 Mechanical property requirements do not apply to
tubing smaller than
1
⁄
8
in. [3.2 mm] in inside diameter or 0.015
in. [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 stated
in the order.
1.6 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 may not be exact equivalents; therefore, each system
shall be used independently of the other. Combining values
from the two systems may result in non-conformance with the
standard. 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 the
test method described in the Supplementary Requirements of
this specification. This standard does not purport to address all
of the safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appro-
priate safety, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use. A
specific warning statement is given in Supplementary Require-
ment S7, Note S7.1.
1.8 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
