Kub dov hlau yog muab faib ua cov qauv hlau, me me steel thiab welded raj mis steel.Tom qab ntawd, raws li ntau yam steels, nrhiav cov hlau koj xav tau, thiab xyuas qhov ceev thiab muaj pes tsawg leeg ntawm cov hlau tshwj xeeb.Kub dov steel phaj muaj tsawg hardness, yooj yim ua thiab zoo ductility.Txias dov phaj hardness yog siab, kev ua haujlwm yog qhov nyuaj, tab sis tsis yooj yim rau deformation, siab zog.Kub dov steel phaj muaj lub zog qis thiab tsis zoo ntawm qhov chaw (tsis tshua muaj oxidation tiav), tab sis zoo plasticity.Feem ntau rau nruab nrab tuab phaj, txias dov phaj, siab zog, siab hardness, siab nto tiav, feem ntau rau nyias phaj, yuav siv tau raws li xuas nrig ntaus phaj.Cov txheej txheem ntau lawm ntawm kub-kuav los tiag steel phaj yog txawv ntawm qhov txias-dov hlau phaj.Kub dov steel phaj yog kub dov, txias dov steel phaj yog chav tsev kub frying
