Anopfuura mabhiriyoni 1,5 matani esimbi anogadzirwa gore negore, ayo anoshandiswa kugadzira zvakasiyana-siyana zvezvigadzirwa, zvakadai setsono dzokusonesa uye matanda ezvivakwa zvezvivako zvine skyscrapers.Carbon simbi ndiyo inonyanya kushandiswa alloy simbi, inoverengera inosvika 85% yezvese kugadzirwa kweUS.Iyo kabhoni yemukati yechigadzirwa iri muchikamu che 0-2%.Iyi kabhoni inokanganisa iyo microstructure yesimbi, ichipa iyo ine mukurumbira simba uye kuoma.Aya alloys anewo mashoma manganese, silicon uye mhangura.Simbi yakapfava ndiyo izwi rekutengesa resimbi yakapfava ine kabhoni yemukati muhuwandu hwe0.04-0.3%.
Carbon simbi inogona kuiswa zvichienderana nemakemikari anoumbwa uye zvimiro zvechigadzirwa.Simbi yakapfava zvakare inowira muchikamu chesimbi chakapfava nekuti ine yakafanana kabhoni yemukati.Ordinary carbon steel haina alloys uye inogona kukamurwa muzvikamu zvina:
1. Low carbon steel
Simbi yakapfava ine kabhoni ye0.04-0.3% uye ndiyo yakajairika giredhi yekabhoni simbi.Simbi yakapfava inonziwo simbi yakapfava sezvo ichitsanangurwa seine kabhoni yakaderera ye 0.05-0.25%.Simbi yakapfava iductile, inogoneka zvakanyanya uye inogona kushandiswa mumotokari nhengo dzemuviri, shizha uye waya zvigadzirwa.Kumucheto kwakakwirira kweiyo yakaderera kabhoni yemukati renji, pamwe neanosvika 1.5% manganese, iyo mechaniki zvivakwa inokodzera zvitambi, forgings, isina musono machubhu uye boiler ndiro.
2. Medium carbon steel
Medium carbon steels ane kabhoni yemukati muhuwandu hwe 0.31-0.6% uye manganese emukati muhuwandu hwe 0.6-1.65%.Simbi iyi inogona kupiswa nekudzimwa kuti iwedzere tune iyo microstructure uye michina zvinhu.Zvishandiso zvakakurumbira zvinosanganisira ma axles, ekisi, magiya, njanji uye mavhiri enjanji.
3. High carbon steel
High carbon steel ine carbon content ye 0.6-1% uye manganese ye 0.3-0.9%.Izvo zvinhu zvepamusoro kabhoni simbi inoita kuti ive yakakodzera kushandiswa sezvitubu uye yakakwirira simba waya.Zvigadzirwa izvi hazvigone kuiswa welded kunze kwekunge yakadzama yekurapa kupisa maitiro inosanganisirwa mune welding maitiro.High carbon steel inoshandiswa pakucheka maturusi, high simba waya uye zvitubu.
4. Ultra-yakakwirira kabhoni simbi
Ultra-yakakwirira kabhoni simbi ine kabhoni ye1.25-2% uye inozivikanwa seyekuedza alloys.Tempering inogadzira simbi yakaoma kwazvo, iyo inobatsira pakushandisa senge mapanga, ekisi kana zvibhakera.
