TP347H Likarolo tsa phala e entsoeng ka tšepe e sa hloekang li kenyelletsa:

Matla a mocheso: e ntse e ka boloka thepa e ntle ea mochini mocheso o phahameng.

Ho hanyetsa intercrystalline corrosion: ka ho eketsa niobium (Nb) e le stabilizer, intercrystalline corrosion e thibeloa ka katleho.

Corrosion resistance: e bonts'a khanyetso e ntle ea kutu ho alkaline, metsi a leoatle le libaka tse fapaneng tsa asiti.

Ts'ebetso ea welding: e loketseng ts'ebetso ea welding, e ka netefatsa boleng le bots'epehi ba weld.

Mabapi le ts'ebeliso, phala ea tšepe e sa hloekang ea TP347H e sebelisoa haholo setsing sa jenereithara, li-boiler superheater tube, reheater tube, pipe ea mouoane le mocheso oa mocheso oa petrochemical le mocheso o mong o phahameng le tikoloho ea khatello e phahameng. Ho feta moo, e loketse maemo a antioxidant, ka mocheso oa eona o lumelletsoeng oa antioxidant ho fihla ho 750 ℃.
