Astm A213 T9 Alloy Steel Tubes - China

alloy tubes T9, heat exchanger tubes,

superheater tubes

ASTM A213 T9 Seamless Ferritic and Austenitic Alloy-Steel

Boiler, Superheater, Heat-Exchanger Tubes.

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.

ASTM A213 T9 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.
