Classified by chemical composition
Carbon steel can be divided into low carbon steel, medium carbon
steel and high carbon steel according to chemical composition (that
is, carbon content).
(1) Low carbon steel
Also known as mild steel, low carbon steel with carbon content from
0.10% to 0.30% is easy to accept various processing such as
forging, welding and cutting, and is often used in the manufacture
of chains, rivets, bolts, shafts, etc.
(2) Medium carbon steel
Carbon steel with a carbon content of 0.25% to 0.60%. There are
killed steel, semi-killed steel, boiling steel and other products.
In addition to carbon, it can also contain a small amount of
manganese (0.70% to 1.20%). According to product quality, it is
divided into ordinary carbon structural steel and high-quality
carbon structural steel. Good thermal processing and cutting
performance, poor welding performance. The strength and hardness
are higher than those of low carbon steel, while the plasticity and
toughness are lower than those of low carbon steel. Hot-rolled and
cold-drawn materials can be used directly without heat treatment,
or they can be used after heat treatment. The quenched and tempered
medium carbon steel has good comprehensive mechanical properties.
The highest hardness that can be achieved is about HRC55 (HB538),
and σb is 600-1100MPa. Therefore, among various uses of medium
strength level, medium carbon steel is the most widely used, in
addition to being used as a building material, it is also widely
used in the manufacture of various mechanical parts.
(3) High carbon steel
Often called tool steel, it has a carbon content from 0.60% to
1.70% and can be hardened and tempered. Hammers, crowbars, etc. are
made of steel with a carbon content of 0.75%; cutting tools such as
drills, taps, reamers, etc. are made of steel with a carbon content
of 0.90% to 1.00%.
