Uhlobo 347H insimbi engagqwali ye-carbon austenitic chromium ephezulu. Kutholwe ezinhlelweni ezidinga ukumelana nokushisa okuphezulu, ezinye izici ezinkulu zokuklama zihlanganisa:
- Ukumelana okufanayo nokuvikela ukugqwala njenge-Alloy 304
- Isetshenziselwa izinto ezishiselwe kakhulu uma ukuhushula kungenzeki
- Ukumelana kahle ne-oxidation, ngokuhambisana nezinye izinsimbi ezingenasici ze-austenitic
- Ikhabhoni ephezulu ivumela izindawo ezingcono zokushisa okuphezulu
Ngenxa yezakhiwo ezihlukile zoHlobo lwe-347H isetshenziswa ekusetshenzisweni okuhlukahlukene ezimbonini eziningi zanamuhla ezibalulekile:
- Amashubhu e-boiler nama-casings
- Amapayipi okuhluza uwoyela negesi
- Ama-superheaters akhazimulayo
- Amapayipi omusi anengcindezi ephezulu
- Amashubhu okushintsha ukushisa
- Ama-heaters ekhabetheni
- Imishini eshiselwe odongeni esindayo
- Izitaki ze-aircraft exhaust kanye nezindandatho zokuqoqa
Kanye nezinga eliphakeme lekhabhoni bese kuba Uhlobo 347 olujwayelekile, Uhlobo lwensimbi engagqwali engu-347H lunokwakheka kwamakhemikhali okuhlukile okuhlanganisa okulandelayo:
- Fe ibhalansi
- Cr 17-20%
- Kuze kube ngu-9-13%
- C 0.04-0.08%
- Mn 0.5-2.0%
- S 0.30% ubuningi
- Singu-0.75% ubuningi
- P 0.03% ubuningi
- Cb/Ta 1% ubuningi
