ASTM A213 TP347 Stainless Steel Seamless Boiler Tube

ASTM A213 covers seamless ferritic and austenitic alloy steel pipe for boilers, superheaters, and heat exchangers. It requires high-temperature performance and nondestructive testing.

TP347 offers high strength and creep resistance at high temperatures. Its excellent oxidation resistance makes it suitable for components exposed to continuous high-temperature environments. In addition to its excellent resistance to intergranular corrosion, it also exhibits good corrosion resistance against a wide range of organic and inorganic acids and alkalines.

Thus, TP347 is a proven and reliable choice for applications involving high temperatures, post-weld use, or temperatures susceptible to sensitization. It is commonly found in core high-temperature equipment in the power generation and petrochemical industries.
