ASTM A213 Seamless Ferritic and Austenitic Alloy-Steel Boiler,
Superheater, and Heat-Exchanger Tubes.
ASTM A213 Standard covers seamless ferritic and austenitic steel boiler,
superheater, and heat-exchanger tubes. 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 tubes shall be made by the seamless process and
shall be either hot finished or cold finished, as specified. Grade TP347HFG
shall be cold finished. Heat treatment shall be done separately and in addition
to heating for hot forming. The ferritic alloy and ferritic stainless steels
shall be reheated. On the other hand, austenitic stainless steel tubes shall be
furnished in the heat-treated condition. Alternatively, immediately after hot
forming, while the temperature of the tubes is not less than the minimum solution
temperature, tubes may be individually quenched in water or rapidly cooled by
other means. Tension test, hardness test, flattening test, and flaring test
shall be done to each tube. Also, each tube shall be subjected to the
nondestructive electric test or hydrostatic test.

ASTM A213 Standard Scope
1.1 This specification covers seamless ferritic and austenitic steel
boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304,
etc. These steels are listed in Tables 1 and 2.
1.2 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.
1.3 The tubing sizes and thicknesses usually furnished to this specification
are 1/8 in. [3.2 mm] in inside diameter to5 in. [127 mm] in outside diameter and 0.015 to0.500 in. [0.4 to12.7 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
1.4 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
