UkuthethelelaIngabe ukucelwa kwe-ingot yensimbi ku-billet ngesando noma ngomshini wengcindezi; ngokusho kokwakheka kwamakhemikhali, insimbi ingahlukaniswa ngensimbi ye-carbon nensimbi ye-alloy

(1) Ngaphezu kwe-Iron ne-Carbon, ukwakheka kwamakhemikhali kwensimbi yekhabhoni futhi kuqukethe izinto ezifana neManganese Silico, isibabule kanye ne-phosphorus, phakathi kwesibabule ne-phosphorus kungukungcola okulimazayo. UManisese Silico uyinto eyenziwe nge-deoxidaged ku-carbon yensimbi kwinqubo yokwenza i-wenyermaking. Ngokuya kokuqukethwe okuhlukile kwekhabhoni ngensimbi yekhabhoni, kuvame ukuhlukaniswa ngezinhlobo ezintathu ezilandelayo:
I-Low Carbon Steel: Okuqukethwe yi-carbon kungu-0.04% -0.25%;
I-Medium Carbon Steel: 0.25% -0.55% okuqukethwe kwekhabhoni;
I-Carbon Steel ephezulu: Okuqukethwe kwekhabhoni kukhulu kune-0.55%
. Futhi izinto zomhlaba ezingavamile njll. Ngaphezu kwalokho, ezinye zensimbi ye-calcium alloy ziqukethe i-boron ne-nitrogen njll

I-Alloy ye-Alloy ephansi: Okuqukethwe okuphelele kwe-Alloy Element kungaphansi kwama-3.5%;
I-Medium Alloy Steel: Okuqukethwe okuphelele kwe-alloying element kungu-3.5-10%;
Insimbi ephezulu ye-Alloy: Okuqukethwe okuphelele kwe-Alloy Okuqukethwe kungaphezulu kwe-10%
Ngokuya ngenani lezakhi ezahlukahlukene ze-alloy eziqukethwe ku-alloy steel, futhi zingahlukaniswa ngensimbi kanambambili ye-tarnary kanye ne-multi-element alloy ngaphezu kwalokho, ngokuya ngezinhlobo ze-alloy eziqukethwe insimbi, zingahlukaniswa ngensimbi, i-chromium, I-Boron Steel, i-Silicon Steel, i-Manganese yensimbi, i-chromium manganese yensimbi, i-molybdenum steel, i-chromium molybdenum, i-tungsten vanadium yensimbi nokunye
