Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes

۱٫ Scope

۱٫۱ This specification2 covers seamless ferritic and austenitic
steel boiler, superheater, and heat-exchanger tubes, designated
Grades T5, TP304, etc. These steels are listed in Tables
۱ and 2.
۱٫۲ 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.
۱٫۳ The tubing sizes and thicknesses usually furnished to
this specification are 1⁄۸ in. [3.2 mm] in inside diameter to 5 in.
[۱۲۷ mm] in outside diameter and 0.015 to 0.500 in. [0.4 to
۱۲٫۷ 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.
۱٫۴ 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
