What material is T12 seamless pipe?

T12 seamless pipe is used for boiler, superheater and heat exchanger tubes with minimum wall thickness. It is suitable for seamless iron and austenitic steel pipes with minimum wall thickness for boilers and superheaters and austenitic steel pipes for heat exchangers.

Chemical composition of T12 seamless pipe: C 0.05-0.15, Si ≤ 0.50, Mn 0.30-0.61, P S ≤ 0.025, Cr 0.80-1.25, Mo 0.44-0.65.

Mechanical properties of T12 seamless pipe: tensile strength ≥ 415 MPa, yield strength ≥ 205 MPa, elongation ≥ 30%.

The main American Standard ASTM A213 steel grades are: A213 T11, A213 T12, A213 T22, etc..

T12 seamless pipe is a steel grade produced according to American Standard ASTM A213, which does not mean that it is produced in the United States. It can be produced by steel mills in other countries according to American Standard ASTM A213, and the quality is the same as that of American Standard.
