This specification covers minimum-wall-thickness, seamless ferritic and austenitic steel, boiler and superheater tubes and austenitic steel heat-exchanger tubes, designated Grades T5, TP304, etc. These steels are listed in the specification .
Optional supplementary requirements are provided and, when desired, shall be so stated in the order.
The tubing sizes and thicknesses 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. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
The values stated in either inch-pound units or SI units are to be regarded separately as standard. (A combination of values from the two systems may result in nonconformance with the specification.) The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
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.

The service temperature is 580 ℃, and the steel plate is required to have high high temperature endurance strength. The steel plate is delivered in the normalized and tempered state. 12Cr1MoVG alloy pipe is based on high-quality carbon structural steel, and one or several alloy elements are appropriately added to improve the mechanical properties, toughness and hardenability of the steel.
