Carbon steel isimbi ine carbon content kubva pa 0.05 kusvika 2.1 percent nehuremu.
Simbi yakapfava (simbi ine chikamu chidiki chekabhoni, yakasimba uye yakaoma asi isingakurumidzi kushatirwa), inozivikanwawo sesimbi-kabhoni simbi uye yakaderera-kabhoni simbi, ndiyo inonyanyo zivikanwa sesimbi nekuti mutengo wayo wakadzikira nepo ichipa. zvinhu zvivakwa zvinogamuchirwa kune akawanda maapplication. Simbi yakapfava ine inenge 0.05–0.30% kabhoni. Simbi yakapfava ine simba rakaderera, asi yakachipa uye iri nyore kugadzira; kuoma kwepamusoro kunogona kuwedzerwa kuburikidza ne carburizing.
Nhamba Nhamba: GB/T 1591 Yakakwirira simba yakaderera alloy zvimiro simbi
