If they contain over about 0.55% carbon, they can be hardened to a high level. However, at the same or even at lower hardness, certain martensitic cast irons (HC 250 and Ni-Hard) can outperform carbon and low alloy steel considerably. For simplicity, each of these alloys can be considered a mixture of hard carbide and hardened steel.
