I-347 iyinsimbi equkethe insimbi engenacala, kanti u-347H yinguqulo yayo ephezulu yekhabhoni. Ngokuya kokwakheka,347kungabonakala njenge-alloy etholakala ngokungeza i-niobium kuya kwisisekelo sensimbi engama-304 engagqwali. I-Niobium iyinto engavamile yomhlaba esebenza ngokufanayo ku-titanium. Uma kungezwe ku-alloy, kungahlanza isakhiwo sokusanhlamvu, ukwenqaba ukuqina kokusanhlamvu, futhi kukhuthaze ukuqina kweminyaka.

Ⅳ.material impahla
Ukumelana nokugqwala okuqinile okuqhathaniswa nensimbi engama-304 engagqwali.
② Phakathi kuka-427 ~ 816 ℃, kungavimba ukwakheka kwe-chromium carbide, ukwenqaba ukuzwela, futhi kumelana nokuphikiswa okuhle ekugculiseni kolunye uhlangothi.
I-③It isenokumelana okuthile kwe-creep endaweni eqinile ye-oxidizizing yemvelo eshisa kakhulu ka-816 ℃.
Kulula ukunweba nokwakha, kulula ukuwela.
⑤Uhlobo lokushisa oluphansi lokushisa.
