Mofuta oa 347H ke tšepe e sa hloekang ea carbon austenitic chromium. E fumaneha lits'ebetsong tse hlokang ho hanyetsa mocheso o phahameng, likarolo tse ling tse kholo tsa moralo li kenyelletsa:
- Tšireletso e ts'oanang le ts'ireletso ea kutu joalo ka Alloy 304
- E sebelisoa bakeng sa lisebelisoa tse boima tse cheselitsoeng ha annealing e sa khonehe
- Khanyetso e ntle ea oxidation, ha e bapisoa le litšepe tse ling tse ngata tsa austenitic
- K'habone e phahameng e fana ka thepa e ntle ea mocheso o phahameng
Ka lebaka la thepa e ikhethang ea Mofuta oa 347H e sebelisoa mefuteng e fapaneng ea ts'ebeliso ho liindasteri tse ngata tsa bohlokoa tsa kajeno:
- Li-tubes tsa boiler le li-casings
- Liphaephe tsa ho hloekisa oli le khase
- Li-superheaters tse khanyang
- Liphaephe tsa mouoane tse nang le khatello e phahameng
- Li-tubes tse futhumatsang mocheso
- Li-heaters tsa kamore
- Thepa e boima e entsoeng ka lebota
- Lifofane tsa ho qeta mekotla le mehele e bokellang
