Mild steel: carbon content less than 0.25%. because of its lower strength and hardness, it is called mild steel. Low carbon steel is easy to process, including forging, welding and cutting, so it is often used in the manufacture of chains, rivets, bolts, shafts and so on.
Medium carbon steel: carbon content of 0.25% to 0.60%. Compared with mild steel, medium carbon steel has higher strength and hardness, while lower plasticity and toughness. After quenching and tempering, medium carbon steel has good comprehensive mechanical properties and is suitable for medium-strength applications, such as building materials and mechanical parts.
High carbon steel: Carbon content is more than 0.60%. High carbon steels is often used to make tool steels because it is harder and can be quenched and tempered to increase hardness and wear resistance. High carbon steel has poor weldability and is therefore generally not used in structures that require welding. This type of steel is commonly used to make tools such as hammers and crowbars, as well as cutting tools such as drills, taps and reamers.
In summary, the main difference between low carbon steel, medium carbon steel and high carbon steel is their carbon content, which determines their mechanical properties, processing properties and uses
