Carbon steel is a widely used material that is vital to many industries due to its unique properties.
Some of the most common types of carbon steel include low-carbon steel, medium-carbon steel, high-carbon steel, ultra-high carbon steel.
Mild steel has less than 0.25 wt.% carbon and cannot be hardened by heat treatment to form martensite.
Medium carbon steel contains 0.25 to 0.60 wt.% carbon and 0.60 to 1.65 wt.% manganese.
High-carbon steel contains 0.60 to 1.25 wt.% carbon and 0.30 to 0.90 wt.% manganese.
