Hlau yog ib qho txawv ntawm cov hlau uas muaj cov pa roj carbon ntxiv. Cov hlau alloys kuj tseem muaj lwm cov ntsiab lus ntxiv, xws li chromium lossis npib tsib xee, los tsim cov khoom tshwj xeeb. Ib txoj hauv kev npaj cov hlau rau kev ua lag luam yog hu ua txias dov.
--- Kev tsim khoom
Cold rolled steel yog tsim los ntawm kev hla cov hlau los ntawm ntau lub chais tom qab nws tau txias los ntawm kev tsim khoom thawj zaug. Raws li cov hlau dhau los ntawm cov chais, nws cov tuab yog maj mam txo.
--- Hom
Feem ntau muaj plaub hom txias dov hlau: cov hlau ua lag luam, kos hlau, cov hlau sib sib zog nqus ntxiv, thiab cov hlau sib sib zog nqus ntxiv. Drawn steel yog ntau ductile.
--- Qhov zoo
Cold rolled steel nyiam muaj cov ntsiab lus qis dua li cov hlau kub kub, ua rau nws ruaj khov dua. Lawv tuaj yeem muab dov rau ntau qhov tshwj xeeb vim tias cov hlau kub kub tsis ntsws.
--- Lub zog
Raws li KeytoMetal.com, txias dov hlau kuj tuaj yeem kho kom muaj zog ntawm cov qauv. Txawm li cas los xij, SteelStrip.co.uk tshaj tawm tias kev ua kom muaj zog thiab hardness txo ductility.
--- Kev kho deg thiab zoo li
Cold dov steel feem ntau yog dov kom muaj qhov zoo li matte. Lawv kuj tuaj yeem pleev xim rau, yog tias xav tau, los ntawm kev tshem cov roj nplaum uas feem ntau siv ua ntej kev thauj mus los.
