ASTM A210 / ASME SA210 Seamless Tubes Specification

Carbon Steel Seamless Tubes for Boilers & Heat Exchangers | Technical Specification PDF Download

The ASTM A210 / ASME SA210 Seamless Tubes Specification PDF provides a complete technical reference for carbon steel seamless tubes used in boilers, superheaters, heat exchangers, and other high-temperature pressure applications. This specification covers material grades, chemical composition, mechanical properties, manufacturing processes, dimensional tolerances, testing requirements, and typical applications.

Standard Overview: ASTM A210 & ASME SA210

ASTM A210 is a widely used international standard that specifies seamless medium-carbon steel tubes intended for boiler and heat exchanger service.

ASME SA210 is the ASME equivalent of ASTM A210 and is commonly required for pressure vessel, power plant, and boiler projects built in accordance with ASME Boiler and Pressure Vessel Code (BPVC).

These two standards are technically equivalent in terms of material requirements and performance.

Grades Under ASTM A210 / ASME SA210

ASTM A210 / ASME SA210 includes the following commonly supplied grades:

Grade A1 – Most widely used grade for boiler and heat exchanger tubes
Grade C – Higher strength grade for more demanding pressure applications

Both grades are supplied as seamless carbon steel tubes and are suitable for elevated temperature service.

Material Description

Material Type: Carbon Steel
Manufacturing Method: Seamless
Product Form: Steel Tubes / Pipes
Delivery Condition: Hot finished or cold drawn

ASTM A210 / ASME SA210 seamless tubes are designed to provide uniform wall thickness, excellent pressure resistance, and reliable performance under thermal stress.

Carbon, max	0.27	0.35
Manganese	0.93 max	0.29–1.06
Phosphorus, max	0.035	0.035
Sulfur, max	0.035	0.035
Silicon, min	0.1	0.1
Note	For each 0.01% C below max, Mn +0.06% allowed up to 1.35%

Mechanical Properties (Minimum Requirements)

Property	Grade A-1	Grade C
Tensile strength, min	60 ksi (415 MPa)	70 ksi (485 MPa)
Yield strength, min	37 ksi (255 MPa)	40 ksi (275 MPa)
Elongation in 2 in or 50 mm, min	30 %	30 %
Elongation reduction per 1/32 in under 5/16 in	1.50 %	1.50 %
Using 4D gage length	22 %	20 %

Manufacturing Process

ASTM A210 / ASME SA210 seamless tubes are produced through:

Hot rolling or cold drawing
Heat treatment in accordance with the specification
Straightening, sizing, and cutting to length
Final inspection and testing

The seamless manufacturing process eliminates weld seams, improving reliability in pressure applications.

Dimensions & Tolerances

Outside Diameter (OD): As specified in ASTM A210 / ASME SA210
Wall Thickness (WT): As specified
Length: Random length, double random length, or fixed cut length

Dimensional tolerances strictly comply with the standard requirements.

Testing & Inspection

Each ASTM A210 / ASME SA210 seamless tube may undergo:

Chemical analysis
Tensile and elongation tests
Flattening or flaring tests
Hydrostatic testing or non-destructive testing (NDT)
Dimensional and visual inspection

Mill Test Certificates (EN 10204 3.1) are normally supplied.

Applications

Power Plant Boilers
Industrial Boilers
Heat Exchangers
Superheaters
Economizers
Pressure Vessels

ASTM A210 / ASME SA210 seamless tubes are extensively used in energy, power generation, and thermal engineering industries.
