Izici:
1.Ishubhu yensimbi ye-carbon ephansingokungenamthungoiyinsimbi ye-carbon ene-carbon content engaphansi kuka-0.25%.Ibizwa nangokuthi insimbi emnene ngenxa yamandla ayo aphansi, ubulukhuni obuphansi nokuthambile.
2. Isakhiwo esihlanganisiwe seshubhu yensimbi ye-carbon ephansi ene-seamless i-ferrite kanye nenani elincane le-pearlite, elinamandla aphansi nobulukhuni, ne-plasticity enhle nokuqina.
3. Ishubhu yensimbi enekhabhoni ephansi engenamthungo inokwakheka okuhle okubandayo futhi ingabanda okwakhiwa ngokugoqa, ukugoba, ukunyathela, njll.
4. Ishubhu yensimbi ye-carbon ephansi engenamthungo inokushisela okuhle.Kulula ukwamukela ukucutshungulwa okuhlukahlukene njengokubumba, ukushisela nokusika.

Ukwelashwa kokushisa:
Ishubhu yensimbi ye-carbon ephansi engenamthungo inomkhuba omkhulu wokuguga, kokubili ukuthambekela kokucisha nokuguga, kanye nokuguga nokuguga.Lapho insimbi ipholile ekushiseni okuphezulu, i-carbon ne-nitrogen ku-ferrite i-supersaturated, futhi i-carbon ne-nitrogen ensimbi ingakhiwa kancane kancane ekushiseni okujwayelekile, ukuze amandla nobulukhuni bensimbi kuthuthukiswe, kanye ne-ductility. nokuqina kuyehliswa.Lesi simo sibizwa ngokuthi ukuguga quenching.Amashubhu ensimbi ekhabhoni ephansi angenamthungo azoba nomthelela wokuguga ngisho noma engacimi.Ukuguqulwa kweshubhu yensimbi ye-carbon ephansi engenamthungo kukhiqiza inani elikhulu lokuhlukaniswa.Ama-athomu e-carbon ne-nitrogen ku-ferrite asebenzisana ngokunwebeka ngokugudluka, futhi ama-athomu ekhabhoni nawe-nitrogen abuthana emigqeni yokugudluka.Le nhlanganisela yama-athomu ekhabhoni ne-nitrogen kanye nemigqa yokugudluka ibizwa nge-Cochrane gas mass (Kelly gas mass).Yandisa amandla nobulukhuni bensimbi futhi inciphisa i-ductility nokuqina.Lesi simo sibizwa ngokuthi ukuguga kwe-deformation.Ukuguga kwe-deformation kuyingozi kakhulu ku-ductility kanye nokuqina kwe-carbon steel ephansi kunokuqeda ukuguga.Kukhona amaphuzu asobala aphezulu naphansi esivuno kwijika eliqinile lensimbi ye-carbon steel.Kusukela endaweni yokukhiqiza ephezulu kuze kube sekupheleni kwesandiso sesivuno, ibhande lokushwabana elingaphezulu elakhiwe phezu kwesampula ngenxa yokuguquguquka okungalingani libizwa ngokuthi ibhande le-Rydes.Izingxenye eziningi zokugxiviza zivame ukulahlwa.Kunezindlela ezimbili zokuyivimbela.Indlela ephezulu ye-pre-deformation, insimbi ekhubazekile ibekwe isikhathi esithile futhi ibhande le-Rudes nalo likhiqizwa lapho kugxilwa, ngakho-ke insimbi ekhubazekile akufanele ibekwe isikhathi eside ngaphambi kokunyathela.Okunye ukufaka i-aluminium noma i-titanium ensimbi ukuze kwakhiwe inhlanganisela ezinzile ne-nitrogen ukuvimbela ukuguga kokuguga okubangelwa ukwakheka kwe-Kodak air mass.
