Insimbi ye-carbon ejwayelekile, eyaziwa nangokuthi i-iron carbon alloy, ihlukaniswe ngensimbi ye-carbon ephansi (ezobizwa ngokuthi insimbi ecijile), insimbi ye-carbon steel ne-cast iron ngokusho kokuqukethwe kwekhabhoni.Ngokuvamile, lezo ezinekhabhoni engaphansi kuka-0.2% zibizwa nge-low carbon steel, ngokuvamile eyaziwa ngokuthi insimbi ekhandiwe noma insimbi emsulwa;Insimbi enokuqukethwe kwe-0.2-1.7%;I-pig iron enokuqukethwe okungaphezu kuka-1.7% ibizwa nge-pig iron.
Insimbi engagqwali iyinsimbi enokuqukethwe kwe-chromium engaphezu kuka-12.5% kanye nokumelana okuphezulu nokugqwala kwangaphandle (i-asidi, i-alkali nosawoti).Ngokusho kwe-microstructure kunsimbi, insimbi engagqwali ingahlukaniswa ibe i-martensite, i-ferrite, i-austenite, i-ferrite austenite kanye nemvula eyenza lukhuni insimbi engagqwali.Ngokwezinhlinzeko zezinga likazwelonke le-gb3280-92, kukhona izinhlinzeko ezingama-55 sezizonke.
