Chitsulo chochepa cha carbon, chomwe chimatchedwanso mild steel, ndi gulu la chitsulo chopangidwa ndi chitsulo chokhala ndi carbon monga ma alloying elements koma mpweya wa carbon ndi wosakwana 0.25%. Chifukwa cha mphamvu yake yochepa, kuuma kochepa ndi kufewa, imatchedwanso chitsulo chochepa. Zimaphatikizapo zitsulo zambiri za carbon structural ndi zina zapamwamba za carbon structural steels. Ambiri aiwo amagwiritsidwa ntchito popanga uinjiniya popanda chithandizo cha kutentha, ndipo ena amagwiritsidwa ntchito pamakina omwe amafunikira kukana kukana pambuyo pa carburizing ndi mankhwala ena otentha.
Mapangidwe a annealed of low carbon steel ndi ferrite ndi pearlite pang'ono, mphamvu zake ndi kuuma kwake ndizochepa, ndipo pulasitiki yake ndi kulimba kwake kuli bwino. Chifukwa chake, kuzizira kwake ndikwabwino, ndipo kumatha kupangidwa mozizira ndi njira monga crimping, kupindika, ndi kupondaponda. Chitsulo ichi chilinso ndi weldability wabwino. Chitsulo chochepa cha carbon nthawi zambiri chimatanthawuza chitsulo chokhala ndi mpweya wapakati pa 0.10 ndi 0.25%. Chitsulo chamtunduwu chimakhala ndi kuuma kochepa komanso pulasitiki yabwino. Ndi yabwino kutengera ozizira pulasitiki mapindikidwe kupanga ndondomeko, kuwotcherera ndi kudula. Nthawi zambiri amagwiritsidwa ntchito kupanga maunyolo, ma rivets, ma bolts, shafts, etc.
Mapangidwe a annealed of low carbon steel ndi ferrite ndi pearlite pang'ono, mphamvu zake ndi kuuma kwake ndizochepa, ndipo pulasitiki yake ndi kulimba kwake kuli bwino. Chifukwa chake, kuzizira kwake ndikwabwino ndipo kumatha kupangidwa mozizira ndi njira monga crimping, kupindika, ndi kupondaponda. Chitsulo ichi chili ndi weldability wabwino. Chitsulo chochepa cha carbon chokhala ndi mpweya wochepa kwambiri chimakhala ndi kuuma kochepa komanso kusakwanira bwino. Normalizing mankhwala akhoza kusintha machinability ake.
Chitsulo chotsika cha carbon nthawi zambiri chimakulungidwa kukhala zitsulo zokhala ndi ngodya, chitsulo chachitsulo, chitsulo cha I-mtengo, chitoliro chachitsulo, chingwe chachitsulo kapena mbale yachitsulo, yomwe imagwiritsidwa ntchito popanga zida zosiyanasiyana zomangira, zotengera, mabokosi, mabwalo ang'anjo ndi makina aulimi. Chitsulo chapamwamba kwambiri cha carbon chochepa chimakulungidwa m'mbale zopyapyala kuti apange zinthu zozama kwambiri monga ma cab agalimoto ndi ma hood a injini; imakulungidwanso m'mipiringidzo kuti ipange zida zamakina zomwe zimakhala ndi mphamvu zochepa. Chitsulo chotsika kaboni nthawi zambiri sichitenthedwa chisanagwiritsidwe ntchito. Chitsulo chopangidwa ndi carburized kapena cyanidized chokhala ndi mpweya woposa 0.15% chimagwiritsidwa ntchito pazitsulo, bushings, sprockets ndi mbali zina zomwe zimafuna kutentha kwapamwamba komanso kukana kuvala bwino.
Kugwiritsa ntchito chitsulo chochepa cha carbon ndi choletsedwa chifukwa cha mphamvu zake zochepa. Kuchulukitsa koyenera kwa manganese muzitsulo za kaboni, ndikuwonjezera kuchuluka kwa zinthu zophatikizika monga vanadium, titaniyamu, niobium, ndi zina zotere, kumatha kukulitsa mphamvu yachitsulocho. Ngati mpweya wa carbon muzitsulo umachepetsedwa ndi aluminium pang'ono, pang'ono pang'ono za boron ndi carbide kupanga zinthu zimawonjezeredwa, gulu la ultra-low carbon bainite lingapezeke lomwe liri ndi mphamvu zambiri ndikusunga pulasitiki bwino ndi kulimba.
The mpweya zili kuponyedwa otsika mpweya zitsulo ndi zosakwana 0,25%, pamene zili mpweya kuponyedwa sing'anga zitsulo mpweya zitsulo ndi pakati pa 0,25% ndi 0,60%, ndi zili mpweya kuponyedwa mkulu mpweya zitsulo ndi pakati pa 0,6% ndi 3.0%. Mphamvu ndi kuuma kwa chitsulo choponyera kaboni kumawonjezeka ndi kuchuluka kwa kaboni.
Chitsulo cha kaboni cha Cast carbon chili ndi izi zabwino: mtengo wotsika wopanga, mphamvu yayikulu, kulimba bwino komanso pulasitiki wapamwamba. Chitsulo cha kaboni chotayira chitha kugwiritsidwa ntchito kupanga zida zonyamula katundu wolemetsa, monga zitsulo zogudubuza mphero ndi ma hydraulic press bases mumakina olemera. Itha kugwiritsidwanso ntchito kupanga magawo omwe amakhudzidwa ndi mphamvu zazikulu komanso mphamvu, monga mawilo, ma couplers, ma bolster ndi mafelemu am'mbali pamagalimoto apanjanji.
