Insimbi ingahlukaniswa ibe yi-low carbon steel, i-medium carbon steel kanye ne-high carbon steel. Insimbi ye-carbon ephansi - okuqukethwe kwekhabhoni ngokuvamile kungaphansi kuka-0.25%; i-medium carbon steel - okuqukethwe kwekhabhoni ngokuvamile kuphakathi kuka-0.25 no-0.60%; high carbon steel - okuqukethwe kwekhabhoni ngokuvamile kungaphezu kuka-0.60%.
