Inotonhora-yakakungurutswa kabhoni simbi ndiro inogadzirwa nekabhoni simbi ndiro mushure mekutonhora-yakakungurutswa kugadzirisa.Zvikamu zvayo zvikuru isimbi, kabhoni, manganese, sarufa uye phosphorus.Zviri mukati kabhoni zvinowanzova pakati pe0.05% ne0.25% uye ndicho chikamu chikuru chesimbi inotonhora-yakakungurutswa kabhoni.
Cold-akakungurutswa kabhoni simbi ndiro inoshandiswa zvakanyanya mumotokari, kuvaka, midziyo yemagetsi, michina, fenicha, kurongedza nemimwe minda.Mukugadzirwa kwemotokari, kutonhora-yakaputirwa carbon steel plate inowanzoshandiswa kugadzira muviri, chassis uye gonhi, nezvimwewo. Mukugadzira michina, inotonhora-yakaputirwa carbon steel plates inoshandiswa sezvigadzirwa zvekugadzira zvemichina, midziyo yekumanikidza, ngarava nezvimwe zvakadaro.
Muchidimbu, inotonhora-yakakungurutswa kabhoni simbi ndiro ine zvakanakira kusimba kwepamusoro, kuumbwa kwakanaka uye yakafara minda yekushandisa, uye yakakosha simbi yekugadzira zvinhu.
