ASTM A210/A210M Standard Specification for Seamless Medium-Carbon Steel Boiler and Superheater Tubes
ASTM A210 / ASME SA210 is available in A210 Grade A1, and A210 Grade C.
Download PDFThis specification covers seamless medium-carbon steel boiler and superheater tubes. The specification also covers minimum-wall-thickness, tubing sizes, boiler flues including safe ends, arch and stay tubes. The specification provides tensile and hardness properties but only applicable to certain size limitations. Material manufacturing shall be killed. Tubes shall be made by seamless process, marked as either hot-finished or cold-finished. Surface condition shall be specifically stated in the order. Chemical composition shall conform to the requirements. Elemental composition other than listed here shall not be permitted. Tension test, flattening test, flaring test, hardness test, hydrostatic or nondestructive electric test shall be made on specimens. Superheater tubes shall be formed without defects and shall withstand expansion, beading, forging, welding, and bending.
ASTM A210/A210M is a specification that covers seamless and welded carbon steel boiler and superheater tubes. These tubes are designed for high-temperature environments and are employed in applications like power plants and industrial processes.
ASTM A210/A210M tubes are essential for applications requiring reliable performance in high-temperature and high-pressure environments. Their carbon steel composition and the availability of seamless and welded options make them suitable for various industrial applications.
1.1 This specification2 covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends (see Note 1), arch and stay tubes, and superheater tubes.
NOTE 1: This type is not suitable for safe ending by forge welding.
1.2 The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.500 in. [0.9 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.
1.3 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.
1.4 This specification covers grades A-1 and C of Seamless Medium-Carbon Boiler and Superheater Tubes with different chemical and tensile requirements. (Table 1, Table 3, and Section 11.)
1.5 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 are not exact equivalents; therefore, each system must be used independently of the other. Combining 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.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
(1)Tension Test—One tension test shall be made on a specimen for lots of not more than 50 tubes. Tension tests shall be made on specimens from two tubes for lots of more than 50 tubes.
(2)Flattening Test—One flattening test shall be made on specimens from each end of one finished tube from each lot.
(3)Flaring Test—One flaring test shall be made on speci- mens from each end of the one finished tube from each lot.
(4)Hardness Test—Brinell or Rockwell hardness tests shall be made on specimens from two tubes from each lot.
(5)Hydrostatic or Nondestructive Electric Test—Each tube shall be subjected to the hydrostatic.
One flattening test shall be made on specimens from each end of one finished tube from each lot, but not the one used for the flaring test. Tears or breaks occurring at the 12 or 6 o’clock positions on Grade C tubing with sizes of 2.375 in. [60.3 mm] in outside diameter and smaller shall not be considered a basis for rejection.
One flaring test shall be made on specie- men from each end of the one finished tube from each lot, but not the one used for the flattening test.
Orders for ASTM A210 / A210M, ASME SA210 should include the following, as required, to describe the desired material adequately:
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
