Carbon steel yog hom hlau uas muaj cov ntsiab lus carbon ntau dua li lwm hom hlau. Cov ntsiab lus ntawm cov pa roj carbon steel feem ntau yog nyob ntawm {{{0}}.05% mus rau 2.0%, nyob ntawm qib thiab xav siv. Qhov sib ntxiv ntawm cov pa roj carbon rau hlau ua rau nws cov tawv tawv thiab lub zog, ua rau nws feem ntau muaj zog dua li cov hlau me me lossis cov pa roj carbon tsawg.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lo lus "steel" yog ib pawg dav uas suav nrog ntau yam alloys nrog ntau yam sib txawv thiab cov khoom.
Ntau hom hlau tuaj yeem tsim kom muaj cov yam ntxwv sib txawv nyob ntawm lawv qhov kev thov.
Hauv kev sib piv rau lwm hom hlau, carbon steel tuaj yeem muaj zog dua vim nws cov ntsiab lus carbon ntau dua. Nws feem ntau yog siv rau hauv cov ntawv thov uas lub zog thiab qhov nyuaj yog qhov tseem ceeb, xws li hauv kev tsim kho, qhov chaw tsheb, thiab cov cuab yeej. Txawm li cas los xij, nws tsim nyog hais tias muaj lwm yam ntxiv nrog rau cov ntsiab lus carbon uas tuaj yeem cuam tshuam lub zog ntawm cov hlau, xws li muaj lwm cov ntsiab lus alloying thiab cov txheej txheem kev kho cua sov tshwj xeeb siv.
Yog li, thaum carbon steel feem ntau muaj zog dua me me lossis qis-carbon steels, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov qib tshwj xeeb thiab cov khoom sib xyaw ntawm cov hlau tau muab piv los txiav txim siab nws cov txheeb ze zog.
