Kub dov hlau yog dov los ntawm cua sov ntawm qhov kub thiab txias. Nws lub zog tsis yog siab heev, tab sis nws tuaj yeem ua tau raws li peb cov kev xav tau. Nws muaj zoo plasticity thiab weldability; Cold rolled steel yog ib hom zoo tib yam kub dov hlau uas tau raug kos dhau ntawm cov txheej txheem hardening. Nws muaj lub zog siab, tab sis tsis zoo toughness, weldability, hardness thiab brittleness. Kub dov yog ua tiav ntawm qhov kub thiab txias. Kub dov yog txheej txheem ntawm cov khoom cua sov thaum lub sij hawm los yog ua ntej steel dov. Feem ntau, dov yog nqa tawm tom qab cua sov kom siab dua qhov kub ntawm recrystallization.
Cov khoom kub dov tau dav siv hauv nkoj tsim, tsheb, choj, kev tsim kho, tshuab, siab nkoj thiab lwm yam kev lag luam vim lawv lub zog siab, zoo toughness, ua tau yooj yim thiab zoo weldability.
