Astm A213 T9 Alloy Steel Tubes - Chinaprice: contact company for price
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.
