Zingaphezu kwe-1.5 yeebhiliyoni zeetoni zentsimbi eziveliswa minyaka le, ezisetyenziselwa ukwenza iimveliso ezahlukeneyo, ezifana neenaliti zokuthunga kunye nemiqadi yezakhiwo ze-skyscrapers.Intsimbi yeCarbon yeyona isetyenziswa ngokuqhelekileyo i-alloy steel, ibalwa malunga ne-85% yayo yonke imveliso yase-US.Umxholo wekhabhoni wemveliso ukwi-0-2%.Le khabhoni ichaphazela i-microstructure yentsimbi, inika amandla ayo aziwayo kunye nokuqina.Ezi ngxube ziqulethe ixabiso elincinci le-manganese, i-silicon kunye nobhedu.Intsimbi ethambileyo ligama lentengiso yensimbi epholileyo kunye nomxholo wekhabhoni kuluhlu lwe-0.04-0.3%.
Intsimbi yeCarbon ingahlelwa ngokwemichiza kunye neempawu zemveliso.Intsimbi ethambileyo iphinda iwele kwicandelo lentsimbi ethambileyo kuba inomxholo ofanayo wekhabhoni.Intsimbi yekhabhoni eqhelekileyo ayinayo i-alloys kwaye inokwahlulwa ngokweendidi ezine:
1. Intsimbi yekhabhoni ephantsi
Insimbi ethambileyo inomxholo wekhabhoni we-0.04-0.3% kwaye iyona nqanaba eliqhelekileyo le-carbon steel.Intsimbi ethambileyo ikwabonwa njengentsimbi ethambileyo njengoko ichazwa ngokuba nekhabhoni ephantsi ye-0.05-0.25%.Intsimbi ethambileyo i-ductile, ithambile kakhulu kwaye ingasetyenziswa kumalungu omzimba wemoto, iishiti kunye neemveliso zocingo.Kwisiphelo esiphezulu soluhlu lwekhabhoni ephantsi, kunye ne-1.5% ye-manganese, iimpawu zomatshini zifanelekile kwi-stampings, i-forgings, iityhubhu ezingenamthungo kunye ne-boiler plates.
2. Intsimbi yekhabhoni ephakathi
Iintsimbi zekhabhoni eziphakathi zinomxholo wekhabhoni kwi-0.31-0.6% kunye nomxholo we-manganese kwi-0.6-1.65%.Le ntsimbi inokuthi iphathwe ubushushu kwaye icinywe ukuqhubela phambili i-microstructure kunye neempawu zomatshini.Usetyenziso oludumileyo lubandakanya ii-asi, ii-asi, iigiya, iileyili kunye namavili omzila kaloliwe.
3. Intsimbi yekhabhoni ephezulu
I-carbon steel ephezulu inomxholo wekhabhoni we-0.6-1% kunye nomxholo we-manganese we-0.3-0.9%.Iimpawu zentsimbi yekhabhoni ephezulu zenza ukuba zilungele ukusetyenziswa njengemithombo kunye nocingo olunamandla.Ezi mveliso azikwazi ukuthungwa ngaphandle kokuba inkqubo yonyango yokushisa eneenkcukacha ibandakanyiwe kwinkqubo ye-welding.Insimbi ephezulu yekhabhoni isetyenziselwa izixhobo zokusika, ucingo olunamandla kunye nemithombo.
4. I-Ultra-high carbon steel
I-Ultra-high carbon steels inomxholo wekhabhoni we-1.25-2% kwaye ziyaziwa ngokuba yi-alloys yovavanyo.I-Tempering ivelisa intsimbi enzima kakhulu, eluncedo kwizicelo ezifana neemela, ii-axles okanye iipuntshi.
