ASTM A210 Standard for Seamless Steel Boiler Tubes

ASTM A210 specification covers minimum wall thickness, seamless medium carbon steel, boiler tubes and boiler flues, including safe ends, arch and stay tubes, and superheater tubes. This type is not suitable for safe ending by forge welding.

The steel 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. Steel tubing having other with all other requirements of this specification.

Mechanical properties requirements do not apply to steel tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of Specification ASTM A 520 , shall supplement and supersede the requirements of this specification.

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 value 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.
