Material types of carbon steel coils

Carbon steel coils are mainly made of low carbon steel, medium carbon steel and high carbon steel.
1. Low carbon steel coil
Low carbon steel coil refers to steel with a carbon content of less than 0.05%. This kind of steel has low strength and toughness, but has good plasticity and weldability. Mild steel coils are commonly used in automotive, lightweight structures, pipes and vessels, among other applications. Common low carbon steel coils include Q195, Q215, Q235, etc.
2. Medium carbon steel coil
Medium carbon steel coil refers to steel with a carbon content between 0.25% and 0.60%. This type of steel has high strength and hardness, but low toughness. Medium carbon steel coils are commonly used in automotive, machine building, agricultural machinery and bearings. Common medium carbon steel coils include 20#, 45#, 50#, etc.
3. High carbon steel coils
High carbon steel coil refers to steel with a carbon content exceeding 0.6%. This type of steel has poor toughness, but high strength and hardness. High carbon steel coils are commonly used in areas such as knives, springs, bearings and high-speed shafts. Common high carbon steel coils include 65Mn, 60Si2MnA, 9CrSi, etc.
In addition to the above three types, there are also some special-purpose carbon steel coils, such as stainless steel coils. This kind of steel contains a large amount of chromium to prevent rust, so it is often used to make kitchen utensils, architectural decoration and medical equipment.
In general, carbon steel coils are made of a wide variety of materials, each of which has its own unique physical and chemical properties and is suitable for different applications. When purchasing carbon steel coils, you need to choose the corresponding material according to its specific uses and requirements.
