ASTM A210 grade C carbon steel seamless pipe is medium-carbon steel, serving for boilers and superheaters. A210C is short for A210 grade C, whose equivalent steel grade is ASME SA210 grade C / SA210C. The hardness of ASTM A210 grade C carbon steel seamless pipe A210C boiler tube shall not exceed 89 HRB or 179 HB.

ASTM A210 grade C carbon steel seamless pipe A210C boiler tube size:
Outside diameter: 1/2 in. to 5 in. [12.7 to 127 mm].
The min. wall thickness: 0.035 to 0.500 in. [0.9 to 12.7 mm].
ASTM A210 grade C carbon steel seamless pipe A210C boiler tube with other dimensions can also be furnished, provided the tube complies with all other requirements of the ASTM A210/A210 specification.

ASTM A210 grade C carbon steel seamless pipe A210C boiler tube chemical composition:

For each reduction of 0.01 % below the specified carbon maximum of ASTM A210 grade C carbon steel seamless pipe A210C boiler tube, an increase of 0.06 % manganese above the specified maximum will be permitted up to a maximum of 1.35 %。

ASTM A210 grade C carbon steel seamless pipe A210C boiler tube mechanical property:

The mechanical property requirements do not apply to ASTM A210 grade C carbon steel seamless pipe A210C boiler tube smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

ASTM A210 grade C carbon steel seamless pipe A210C boiler tube shall be either hot-finished or cold-finished, as specified. Hot finished A210 grade C carbon steel seamless pipe needs not be heat treated. Cold finished A210 grade C carbon steel seamless pipe shall be given a subcritical anneal, a full anneal, or a normalizing heat treatment after the final cold finishing process.
