(1) Low carbon steel Also known as mild steel, carbon content from 0.10% to 0.30% low carbon steel is easy to accept a variety of processing such as forging, welding and cutting, commonly used in the manufacture of chains, rivets, bolts, shafts and so on.

(2) Medium carbon steel Carbon steel with a carbon content of 0.25% to 0.60%. There are a variety of products such as killed steel, semi-killed steel, boiling steel. In addition to carbon, it may contain a small amount of manganese (0.70% to 1.20%).     

 (3) High carbon steel Often referred to as tool steel, carbon content from 0.60% to 1.70%, can be hardened and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drill bits, wire taps, reamers, etc. are made of steel with a carbon content of 0.90% to 1.00%.
