ASTM A210/ASME SA210 Grade A1 Seamless Boiler Tube:
ASTM A210 Grade A1 Steel Tubes covers minimum-wall-thickness, Seamless Medium-Carbon Steel, boiler tubes.

Applicable conditions: ASME SA 210 A1 ferritic steel is primarily used for Heat exchanger tubes in critical thermal power plants and waste heat recovery boilers operated in the temperature range of 300°C -400 °C. ASTM 210 A1 ferritic steel pipes are fitted in water walls operating at temperatures around 300-400°C. SA 210A1 has a maximum hardness of 85 HRB (Rockwell B) and is a P1 Material.

ASTM A210/ASME SA210 Grade C Seamless Boiler Tube:

ASME SA-210C is ASME standard steel grade, which is medium carbon steel pipe for boiler and superheater pipe, pearlescent hot strong steel.
 
Applicable conditions: widely used in 300MW, 600MW and other large capacity power station boilers, heating surface piping and header, steam water piping, etc. with working temperature lower than 500 ℃, such as water wall, economizer, low-temperature superheater, etc. SA 210C has a maximum hardness of 89 HRB (Rockwell B) and is a P1 material.

ASTM A210 Grade A1 and Grade C Seamless Boiler and Superheater Tubes 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 in. 0.500 [0.9 to 12.7 mm], inclusive, in minimum wall thickness.

Grade and Chemical Composition (％):

Grade	C	Mn	P	S	Si
A-1	≤0.27	≤0.93	≤0.035	≤0.035	≥0.10
C	≤0.35	0.29-1.06	≤0.035	≤0.035	≥0.10

Mechanical Properties (MPa)：

Manufacture:
ASTM A210 Grade C Seamless Boiler Tube is manufactured in a seamless process and can be hot or cold finished as specified.

Heat treatment
Thermal processed pipes do not require heat treatment.
Cold finished tubes should be subjected to sub-temperature annealing, full annealing or normalizing heat treatment after final cold finishing.

Advantages:
Corrosion resistance and mechanical properties: ASTM A210 seamless pipe has good corrosion resistance and high mechanical strength, suitable for a variety of industrial environments.
Wide application areas: This seamless pipe is widely used in boilers, heat exchangers and high-pressure equipment, etc., and can meet different industrial needs.
Stable market demand: With the increase in real estate and infrastructure projects, the demand for ASTM A210 seamless pipe is also growing, and the market prospects are good.

Quality inspection of ASTM A210/A210M seamless pipe:

The product should meet the requirements of the "Rules for Type Test of Pressure Pipeline Components":
1. Tensile test
Take a sample from each batch of no more than 50 steel pipes for a tensile test. Take a sample from each batch of more than 50 steel pipes for two tensile tests.

2. Flattening test
Take a finished steel pipe from each batch, but not the one used for expansion test, and take a sample from each end for a flattening test. For Grade C steel pipes with an outside diameter equal to or less than 2.375 inches, tears or breaks at 12 o'clock and 6 o'clock are not grounds for scrapping.

3. Expansion test
Take a completed steel pipe from each batch, but not the one used for flattening test, and take samples from each end for an expansion test.

4. Hardness test
Take two steel pipes from each batch for Brinell or Rockwell hardness test.

5. Hydraulic test or non-destructive testing
Each steel pipe must be subjected to hydraulic test. Non-destructive testing can be used instead of hydraulic test upon the purchaser's request.
