Hlau Hlau, ib qho khoom siv hlau, yog siv dav hauv kev lag luam, kev tsim kho, ua liaj ua teb, thiab lub neej txhua hnub vim nws cov khoom siv zoo dua thiab cov txheej txheem zoo. Nws cov kev ua tau txiav txim siab los ntawm nws cov khoom, kev kho mob, thiab cov khoom siv tseem ceeb: tshuaj kho tshuab, tshuaj lom neeg, thiab txheej txheem tshuaj lom neeg, thiab cov txheej txheem tshuaj lom neeg.
Mechanically, Hlau hlau tus muaj High tensile lub zog thiab ib co℃ntawm ductility. Hlau hlau ua los ntawm qis-} hlau hlau (xws li khoov thiab ntswj thiab sib ntswg xws li khi thiab braiding. Siab -} cov hlau xaim hlau xaim, muaj ntau dua lub zog thiab feem ntau siv cov khoom siv siab, xws li hlua hlau. Lub hardness ntawm hlau hlau tuaj yeem hloov kho los ntawm kev kho cua sov (xws li annealing lossis quenching) kom tau raws li cov cai thov sib txawv.
Chemically, Hlau Hlau yog feem ntau tsim ntawm cov hlau (fe), ua rau nws ntxim nyiam rau oxidative corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig huab cua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig kev loj. Txhawm rau txhim kho nws cov kev kho mob corrosion, kev kho cov nplaim xws li galvanizing, tooj plating plating, lossis txheej yas feem ntau siv. Galvanized Hlau Hlau Hlau (piv txwv li, hluav taws xob hluav taws xob lossis kub}}} pa galvanized) thiab noo noo, nthuav dav nws lub neej pabcuam. Nws yog dav siv nyob rau hauv kev tiv thaiv sab nraum zoov tiv thaiv, laj kab, thiab lwm yam kev siv.
Hais txog cov txheej txheem, hlau hlau muaj cov khoom ua haujlwm zoo heev thiab tuaj yeem tsim ua cov khoom sib txawv thiab cov duab los ntawm cov hau kev xws li kos duab, sib ntswg, thiab vuam. Piv txwv li, cov hlau nyias yuav siv tau rau kev coj ua, thaum tuab xaim hlau tuaj yeem siv rau kev tsim kho kev tsim kho. Tsis tas li ntawd, thaum nws lub tshuab hluav taws xob thiab thermal ua haujlwm yuav tsis piv tus tooj liab, hlau hlau tseem muaj cov txiaj ntsig tsawg {2} daim ntawv thov them.
Hauv cov ntsiab lus xaus, cov khoom ntawm cov hlau hlau ua rau nws muaj ntau yam khoom. Nws cov neeg kho zog zog, kev ua haujlwm, thiab corrosion resistance pab txhawb nws cov kev siv. Kev nce qib yav tom ntej hauv cov kws tshawb fawb txuj ci yuav nthuav ntxiv cov ntawv luam hlau los ntawm kev ua haujlwm zoo thiab cov khoom siv tshiab ua kom zoo.
