Uhlobo lwe-347H yintsimbi ephezulu ye-carbon austenitic chromium engenasici. Ifunyenwe kwizicelo ezifuna ukumelana nobushushu obuphezulu, ezinye izinto eziphambili zoyilo ziquka:
- Ukuchasana okufanayo kunye nokukhuselwa kwe-corrosion njenge-Alloy 304
- Isetyenziselwa izixhobo ezidityanisiweyo ezinzima xa i-annealing ingenakwenzeka
- Ukuxhathisa okulungileyo kwi-oxidation, ngokuhambelana nezinye iintsimbi ezingenasici ze-austenitic
- Ikhabhoni ephezulu ivumela iipropathi ezingcono zokukhwela ubushushu obuphezulu
Ngenxa yeempawu ezikhethekileyo ze-347H isetyenziswa kwiintlobo ngeentlobo zesicelo kumashishini amaninzi abalulekileyo namhlanje:
- Iityhubhu ze-boiler kunye ne-casings
- Imibhobho yokucoca i-oyile nerhasi
- Iiheater ezinkulu ezikhanyayo
- Imibhobho yomphunga woxinzelelo oluphezulu
- Iityhubhu zokutshintsha ubushushu
- Izifudumezi zekhabhinethi
- Izixhobo ezinzima ezifakwe eludongeni
- Iinqwelo zokukhupha iinqwelo kunye namakhonkco okuqokelela
Kunye nenqanaba eliphezulu lekhabhoni ngoko Uhlobo oluqhelekileyo lwe-347, Uhlobo lwe-347H yensimbi engenasici inokwakheka kweekhemikhali ezizodwa ezibandakanya oku kulandelayo:
- Fe balance
- Cr 17-20%
- Ngo 9-13%
- C 0.04-0.08%
- Mn 0.5-2.0%
- S 0.30% max
- Si 0.75% max
- P 0.03% ubukhulu
- Cb/Ta 1% max
