Astm A213 T91 Seamless Alloy Tube - China

price: contact company for price

ASTM A213 T91 Standard covers seamless ferritic and austenitic

steel boiler, superheater, and 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 T91 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.
