Tsawg carbon steel kuj hu ua me me hlau. Cov ntsiab lus carbon nyob ntawm {{0}}.10% txog 0.30%. Tsawg carbon steel yog ib qho yooj yim los txais ntau yam kev ua xws li forging, vuam thiab txiav. Nws yog feem ntau siv los tsim cov chains, rivets, bolts, shafts, thiab lwm yam.
Cov pa roj carbon steel nrog cov ntsiab lus carbon tsawg dua 0.25% tseem hu ua cov hlau me me vim nws lub zog tsis tshua muaj zog, tsis tshua muaj hardness thiab softness. Nws suav nrog feem ntau cov pa roj carbon monoxide steel thiab qee qhov zoo carbon structural steel, feem ntau yog siv rau engineering structural yam tsis muaj kev kho cua sov, thiab qee qhov yog siv rau cov khoom siv kho tshuab uas yuav tsum tau hnav tsis kam tom qab carbonization thiab lwm yam kev kho cua sov.
Cov pa roj carbon tsawg feem ntau yog dov rau hauv lub kaum sab xis steel, channel steel, I-beam, steel yeeb nkab, steel sawb thiab steel phaj, thiab yog siv los ua ntau yam khoom siv hauv tsev, ntim, thawv, furnaces thiab machinery, thiab lwm yam.
Cov pa roj carbon nruab nrab yog carbon steel nrog cov ntsiab lus carbon ntawm {{0}}.25% rau 0.60%. Muaj ntau yam khoom xws li tua steel, semi-tua steel, boiled steel thiab hais txog. Ntxiv nrog rau cov pa roj carbon monoxide, nws tseem tuaj yeem muaj me me ntawm manganese (0.70% ~ 1.20%). Raws li cov khoom lag luam zoo, nws tau muab faib ua cov pa roj carbon zoo tib yam thiab cov khoom siv zoo carbon steel. Thermal processing thiab txiav kev ua tau zoo, tab sis qhov kev ua haujlwm vuam tsis zoo. Lub zog thiab hardness yog siab dua cov pa roj carbon tsawg, tab sis cov plasticity thiab toughness yog qis dua cov pa roj carbon tsawg.
Cov pa roj carbon ntau, feem ntau hu ua cov cuab yeej hlau, muaj cov pa roj carbon ntawm {{0}}.60% mus rau 1.70% thiab tuaj yeem ua kom tawv thiab tempered. Rauj, pov thawj, tuav, thiab lwm yam yog ua los ntawm cov hlau nrog cov ntsiab lus carbon ntawm 0.75%; tej cuab yeej xws li laum, kais, reamers, thiab lwm yam yog ua los ntawm steel nrog cov ntsiab lus carbon ntawm 0.90% mus rau 1.00%.
