ASTM A213 Standard covers seamless ferritic and austenitic

steel boiler, superheater, and heat-exchanger tubes.

Our products for ASTM A213 alloy steel tubes have been

listed as follows:

ASTM A213 T91

ASTM A213 T22

ASTM A213 T12

ASTM A213 T11

ASTM A213 T9

ASTM A213 T5

Grades containing the letter H in their designation have

requirements different from those of similar grades not

containing the letter H.

These different requirements

provide higher creep-rupture strength than normally

achievable in similar grades without these different

requirements.

The tubes shall be made by the seamless

process and shall be either hot finished or cold finished,

as specified.

Grade TP347HFG shall be cold finished.

Heat

treatment shall be done separately and in addition to

heating for hot forming.

The ferritic alloy and ferritic

stainless steels shall be reheated.

On the other hand,

austenitic stainless steel tubes shall be furnished in the

heat-treated condition.

Alternatively, immediately after hot

forming, while the temperature of the tubes is not less than

the minimum solution temperature, tubes may be individually

quenched in water or rapidly cooled by other means.

Tension

test, hardness test, flattening test, and flaring test shall

be done to each tube.

Also, each tube shall be subjected to

the nondestructive electric test or hydrostatic test.
