Astm A213 Alloy Steel Tubes And Pipes - China

ASTM A213 Standard covers seamless ferritic and austenitic steel boiler,

superheater, and heat- exchanger tubes.

ASTM A213 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.
