I-440C yentsimbi yentsimbi yentsimbiImveliso esemgangathweni ephambili eyaziwa ngokuba yindibaniselwano yayo ekhethekileyo yokunganyangeki kunye nokunganyangeki. Yenzelwe usapho olungenasithsaba ongenasiseko kwaye lusetyenziswa ngokubanzi kumashishini ahlukeneyo okusebenza kwayo ephezulu.
Umgangatho we-440C yentsimbi engenalo intsimbi kunye nenqanaba lensizi yentsimbi

Nazi ezinye zeengxwaba eziphambili zokwazisa i-440C yentsimbi yentsimbi yentsimbi:
I-1. Ubume: 440C Ibar yensimbi yensimbi yentsimbi ye-chromium (16-18%), i-carbon (i-Carbon (i-Carbon (i-Carbon (i-Carbon (0.95-1.9-1.2.2.2%), kunye ne-silicon, nase molybdenum.
2. Nyanisa ukuxhathisa: 440C I-440C ibar yensimbi idume ngokuchasene nokuchitheka kwayo okugqwesileyo, kukwenza ukuba ilungele ukusetyenziswa kwezixhobo eziphathwayo, izixhobo zokusika, kunye nezinto ezixhaphakileyo.
3. Ukunganyangeki kwe-Colossion: Ngaphandle kokuba yintsimbi ephezulu yecalbon, i-440c ibonakalisa ukunganyangeki kakuhle.
4. Ubunzima kunye namandla: 440C I-Bar engenalo intsimbi inobunzima obugqwesileyo kunye namandla aphezulu, ukubonelela ngobuqili kunye nobomi obude.
