Kukhiqizwa amathani ensimbi angaphezu kwezigidi eziyizinkulungwane ezingu-1,5 unyaka ngamunye, asetshenziselwa ukwenza imikhiqizo ehlukahlukene, njengezinaliti zokuthunga kanye nemishayo yezakhiwo zezakhiwo eziphakeme.I-Carbon steel iyinsimbi esetshenziswa kakhulu ingxubevange, ibalwa cishe ngama-85% ayo yonke imikhiqizo yase-US.Okuqukethwe kwekhabhoni yomkhiqizo kusebangeni elingu-0-2%.Le carbon ithinta i-microstructure yensimbi, inikeze amandla ayo adumile kanye nokuqina.Lawa ma-alloys aqukethe nenani elincane le-manganese, i-silicon nethusi.Insimbi emnene igama lezentengiselwano lensimbi emnene enokuqukethwe kwekhabhoni ebangeni lika-0.04-0.3%.
Insimbi ye-carbon ingahlukaniswa ngokuya ngamakhemikhali kanye nezakhiwo zomkhiqizo.Insimbi emaphakathi nayo iwela esigabeni sensimbi emnene ngoba inokuqukethwe kwekhabhoni okufanayo.I-carbon steel evamile ayinawo ama-alloys futhi ingahlukaniswa ngezigaba ezine:
1. Insimbi ye-carbon ephansi
Insimbi emnene inokuqukethwe kwekhabhoni engu-0.04-0.3% futhi iyibanga elivame kakhulu le-carbon steel.Insimbi emnene nayo ithathwa njengensimbi emnene njengoba ichazwa ngokuthi inekhabhoni ephansi engu-0.05-0.25%.Insimbi ethambile iyi-ductile, ithambile kakhulu futhi ingasetshenziswa ezingxenyeni zomzimba zezimoto, amashidi kanye nemikhiqizo yocingo.Ekupheleni okuphezulu kwebanga lokuqukethwe kwekhabhoni ephansi, kanye nokufika ku-1.5% we-manganese, izakhiwo zemishini zilungele izitembu, ama-forging, amashubhu angenamthungo namapuleti abhayela.
2. Medium carbon steel
Izinsimbi zekhabhoni ezimaphakathi zinokuqukethwe kwekhabhoni ebangeni lika-0.31-0.6% kanye ne-manganese ebangeni lika-0.6-1.65%.Le nsimbi ingaphathwa ngokushisa futhi icinywe ukuze kuthuthukiswe i-microstructure kanye nezakhiwo zemishini.Izicelo ezidumile zifaka ama-ekseli, ama-ekseli, amagiya, ojantshi kanye namasondo kaloliwe.
3. I-carbon steel ephezulu
I-high carbon steel inokuqukethwe kwekhabhoni engu-0.6-1% kanye nokuqukethwe kwe-manganese kuka-0.3-0.9%.Izakhiwo ze-high carbon steel ziyenza ifanelekele ukusetshenziswa njengeziphethu kanye nocingo olunamandla.Le mikhiqizo ayikwazi ukushiselwa ngaphandle uma inqubo enemininingwane yokwelapha ukushisa ifakiwe kunqubo yokushisela.Insimbi enekhabhoni ephezulu isetshenziselwa amathuluzi okusika, ucingo olunamandla amakhulu neziphethu.
4. Insimbi ye-carbon ephezulu kakhulu
Izinsimbi zekhabhoni eziphakeme kakhulu zinekhabhoni engu-1.25-2% futhi zaziwa njengama-alloys okuhlola.I-Tempering ikhiqiza insimbi eqinile kakhulu, ewusizo ekusebenzeni okufana nemimese, ama-axles noma izibhakela.
