Mtundu wa 347H ndi chitsulo chosapanga dzimbiri cha carbon austenitic chromium. Zopezeka m'mapulogalamu omwe amafunikira kukana kutentha kwambiri, mawonekedwe ena akulu amaphatikiza:
- Kukana kofananako ndi chitetezo cha dzimbiri monga Aloyi 304
- Amagwiritsidwa ntchito pazida zowotcherera zolemetsa ngati sizingatheke
- Kukana kwa okosijeni kwabwino, kofanana ndi zitsulo zina zambiri zosapanga dzimbiri za austenitic
- Mpweya wa carbon umapangitsa kuti pakhale kutentha kwapamwamba kwambiri
Chifukwa cha mawonekedwe apadera a Type 347H amagwiritsidwa ntchito mosiyanasiyana m'mafakitale ambiri ovuta masiku ano:
- Machubu a boiler ndi ma casings
- Makina opangira mafuta ndi gasi
- Ma superheaters oyaka
- Mapaipi othamanga kwambiri
- Machubu osinthira kutentha
- Ma heater a kanyumba
- Zida zotchingira khoma zolemera
- Zonyamula ndege ndi mphete zotolera
Pamodzi ndi mulingo wapamwamba wa kaboni ndiye Type 347 wokhazikika, Type 347H chitsulo chosapanga dzimbiri chili ndi mankhwala apadera omwe amaphatikiza izi:
- Fe balance
- Cr 17-20%
- Ndi 9-13%
- C 0.04-0.08%
- Mn 0.5-2.0%
- S 0.30% kuchuluka
- Ndi 0.75% max
- P0.03% kuchuluka
- Cb/Ta 1% max
Zitsulo zonse zosapanga dzimbiri za Type 347H zomwe zimaperekedwa ndi Cepheus Stainless Steel, zimakwaniritsa miyezo yapadziko lonse lapansi kuphatikiza ASTM, ASME, EN, ndi DIN.
