Cov nqi nickel yav tom ntej ntawm LME tau nce ob hnub sib law liag, kaw nag hmo ntawm $ 21,945 / t.
Cov hlau carbon yog ib qho sib xyaw ua ke ntawm cov carbon thiab hlau uas muaj txog li 2.1% carbon los ntawm qhov hnyav. Kev nce cov ntsiab lus carbon ua rau cov hlau tawv thiab lub zog nce ntxiv, tab sis txo qhov ductility. Cov hlau carbon muaj cov yam ntxwv zoo hauv kev tawv thiab lub zog thiab pheej yig dua li lwm cov hlau.
Cov kauj hlau thiab cov kab uas dov tau txias uas muaj cov pa roj carbon yog tsim los ntawm kev siv cov txheej txheem tsim khoom uas hloov tau yooj yim thiab siv dav hauv tsheb, tshuab ntxhua khaub ncaws, tub yees, khoom siv hluav taws xob thiab cov khoom siv hauv chaw ua haujlwm hlau. Los ntawm kev hloov pauv feem pua ​​ntawm cov hlau carbon, nws muaj peev xwm tsim cov hlau nrog cov yam ntxwv sib txawv. Feem ntau, cov pa roj carbon ntau dua hauv cov hlau ua rau cov hlau nyuaj dua, tawg yooj yim dua, thiab tsis yooj yim khoov.
