I-Nickel iwukhiye wezinto ezingavuthiwe zensimbi engagqwali futhi ifinyelela ku-50% wesamba sezindleko.
I-Carbon steel iyingxube yekhabhoni ne-ayoni enekhabhoni efinyelela ku-2.1% ngesisindo.Ukwenyuka kokuqukethwe kwekhabhoni kukhulisa ubulukhuni namandla ensimbi, kodwa yehlisa i-ductility.I-Carbon steel inezinto ezinhle mayelana nobulukhuni namandla futhi ayibizi kakhulu kunezinye izinsimbi.
Amapayipi angenamthungo ensimbi ye-Carbon asetshenziswa kakhulu ekufakweni kwenuzi, ukuhanjiswa kwegesi, i-petrochemical, ukwakha umkhumbi, ama-boilers nezinye izimboni, ezinokumelana nokugqwala okuphezulu kanye nezakhiwo ezinhle zemishini.
