I-347 yi-Niobium-enensimbi ye-austetitic ye-austenitic, ngelixa i-34h yi-carbon yekhabhoni yayo ephezulu. Ngokwemigqaliselo,347inokubonwa njenge-alloy ethathwe kwi-Niobium ukuya kwisiseko sama-304 intsimbi engenasibala. I-Niobium ngumhlaba onqabileyo osebenza ngokufanayo kwi-Titanium. Xa iyongezwa kwi-Alloty, inokuhlaziya ubume benkozo, ukuxhathisa ukhuphelo lwe-infranion, nokukhuthaza ukuqiniswa.

Iipropathi zepropathi
I-Nasscetcellent Sorrosion Ingqungquthela enokuthelekiswa nentsimbi engama-304.
Phakathi kwe-427 ~ 816 ℃, inokuthintela ukwenziwa kwe-CHROMID CACBID, ixhathise imvakalelo, kwaye ixhathise okuhle kwi-insosion engaphakathi.
I-③It isekhona i-curting into ethile ye-cerp kwimo engqongileyo eqinileyo enobushushu obuphezulu we-816 ℃.
I-④easy yokwandisa kunye nefom, kulula ukuyila.
I-⑤good ingena nzulu.
Izihlandlo zokusebenzisa
Ukusebenza kweqondo lobushushu eliphezulu347 & 347hIntsimbi engenanto ibhetele kune-304 ne-321. Isetyenziswe ngokubanzi kwinqwelo moya, i-Petrochemical, iPhepha le-Injini ye-publes, imibhobho yeGurha ye-turbine, kunye nemithwalo emincinci kwaye amaqondo obushushu angagqithi ngaphezulu kwe-850 ° C. Amalungu asebenza phantsi kweemeko, njl.
