ASTM A213 A213M Standard for Seamless Ferritic and Austenitic Alloy-Steel Boiler Superheater Heat Exchanger Tubes

This standard is issued under the ﬁxed designation A213/A 213M; 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 Department of Defense.

ASTM A213 covers seamless ferritic and austenitic steel boiler, Boiler Tube, and heat-exchanger tubes, designated Grades T5, TP304, etc. Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.

The tubing sizes and thickness usually furnished to this speciﬁcation are 1⁄8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if speciﬁed in the order, average wall thickness. Tubing having other diameters may be furnished, provided such tubes comply with all other requirements of this speciﬁcation.

The values stated in either SI units or inch-pound 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.
