Chitsulo cha kaboni chopanda kanthu, chomwe nthawi zambiri chimatchedwa chitsulo cha kaboni, ndi chinthu chofunikira kwambiri mu chitsulokupangaKapangidwe kake ndi chitsulo ndi kaboni, ndipo kamakhala ndi manganese, silicon, sulfure, ndi phosphorous. Kuchuluka kwa kaboni kumadalira kwambiri momwe imagwirira ntchito. Kuchuluka kwa kaboni kochepa kumapanga chitsulo chofewa komanso chofewa. Kuchuluka kwa kaboni kumawonjezera kuuma ndi mphamvu koma kumachepetsa kusinthasintha.
Chitsulo chofewa chimayimira mapeto a carbon steel spectrum otsika. Kawirikawiri chimakhala ndi carbon 0.05–0.25%, n'zosavuta kulumikiza, kupanga mawonekedwe, ndi makina. Kuuma kwake kochepa kumapangitsa kuti chikhale choyenera kugwiritsidwa ntchito pazigawo za kapangidwe kake, zomangamanga, ndi mapaipi achitsulo wamba. Zitsulo zapakati ndi zapamwamba zimakhala ndi carbon 0.25–1.0%. Ndi zolimba koma zochepa, kotero zimagwiritsidwa ntchito kwambiri m'zigawo zamakina, magiya, ndi zida.
Kusiyana pakati pa chitsulo chopanda mpweya ndi chitsulo chofatsa kumamveka bwino pofufuza makhalidwe enaake:
| Katundu | Chitsulo Chofatsa | Chitsulo chapakati/chapamwamba cha kaboni |
| Kaboni Yochuluka | 0.05–0.25% | 0.25–1.0% |
| Kulimba kwamakokedwe | 400–550 MPa | 600–1200 MPa |
| Kuuma | Zochepa | Pamwamba |
| Kutha kupotoka | Zabwino kwambiri | Zochepa |
| Kutha kugwira ntchito | Zabwino | Wocheperako |
| Ntchito Zachizolowezi | Mapaipi, mapepala, zomangamanga | Magiya, zida zodulira, akasupe |
Chitsulo chofatsaChitoliro cha ERWNdi yosavuta kupindika ndi kupotokola. Mosiyana ndi zimenezi, shaft yachitsulo chapakati cha kaboni ndi yolimba kwambiri ndipo imapereka kukana kwakukulu kuvala, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito molimbika kwambiri. Kusiyana kumeneku kumakhudza njira zopangira komanso ntchito zomaliza.
Chitsulo cha kaboni chopanda kanthu chingayerekezeredwenso ndi zinthu zina. Chitsulo chosapanga dzimbiri chili ndi 10.5% ya chromium, chomwe chimapereka kukana dzimbiri mwamphamvu koma pamtengo wokwera, pomwe chitsulo cha kaboni ndi chotsika mtengo kwambiri ndipo chimagwira ntchito bwino ndi chitetezo cha pamwamba monga galvanizing kapena kupaka utoto.
Kudziwa kusiyana kwa kapangidwe ka mankhwala, mawonekedwe a makina, ndi momwe amagwiritsidwira ntchito nthawi zambiri kumathandiza mainjiniya, opanga mapulani, ndi ogula kusankha chitsulo choyenera. Mwachitsanzo, chitsulo chofewa chimakhala chosavuta kupanga ndi kulumikiza, zomwe zimapangitsa kuti chikhale choyenera ntchito zomangamanga.
Komabe, chitsulo chokhala ndi kaboni wambiri chimapirira kupsinjika ndi kuwonongeka, komwe kumayenera kugwiritsidwa ntchito pazinthu zovuta. Pamapeto pake, chitsulo chopanda kaboni chimagwirizanitsa kusinthasintha ndi kugwiritsa ntchito bwino ndalama. Chitsulo chofatsa chimapangitsa kuti kupanga kukhale kosavuta, pomwe mitundu ya kaboni yolimba imapereka kulimba kwabwino. Kumvetsetsa kusiyana kumeneku kumatsimikizira kuti chipangizo chilichonse chimagwira ntchito bwino kwambiri.
