Lub kaum ntse ntse, feem ntau yog hu ua lub kaum sab xis, yog cov hlua ntev ntawm cov hlau nrog ob sab sib txuas ua ke. Lub qub steel yog cov hlau qauv hlau rau kev tsim kho, uas yog ntu yooj yim, tsuas yog siv rau cov txheej txheem. Hauv kev siv, nws yuav tsum muaj weldability weldability, yas deformation ua tau zoo thiab qee yam muaj zog.
