Carbon Steel

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The term "carbon steel" may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels.

Low Carbon Steel – Composition of 0.05%-0.25% carbon and up to 0.4% manganese. Also known as mild steel, it is a low cost material that is easy to shape. While not as hard as higher-carbon steels, its surface hardness can be increased by carburizing.
Medium Carbon Steel – Composition of 0.29%-0.54% carbon with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong with good wear properties.
High Carbon Steel – Composition of 0.55%-0.95% carbon with 0.30%-0.90% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire.
Very High Carbon Steel - Composition of 0.96%-2.1% carbon. Its high carbon content makes it an extremely strong material, though it is brittle and requires special handling.
