Carbon Steel Plate

Carbon steel plate is a metal material composed of iron with a small amount of carbon and possibly other alloying elements. It has high strength, good wear resistance and machinability.

Its carbon content directly affects its hardness and toughness. Low-carbon versions are suitable for applications that require higher plasticity, such as car bodies and pipes; while high-carbon versions are harder and are often used in applications that require high wear resistance, such as knives and springs.

Carbon steel plates are easy to weld, cut and shape, and are widely used in many industries such as construction, machinery manufacturing, automobiles, ships, and petrochemicals.

Quick Detail:

1. Definition and composition

Definition: Carbon steel plate is a type of steel with a carbon content of less than 2.11% and no metal elements are deliberately added. It is also called plain carbon steel or carbon steel. It is mainly composed of iron and contains a small amount of carbon, silicon, manganese, sulfur, phosphorus and other elements.

Composition: The higher the carbon content, the better the hardness and strength of the carbon steel plate, but the plasticity will decrease. The content of other alloying elements (such as silicon, manganese, phosphorus, etc.) will vary according to different uses and manufacturing processes.

2. Characteristics

Mechanical properties: Carbon steel plate has high strength, hardness and good toughness.

Thermal properties: It can still maintain high strength and hardness at high temperatures.

Process performance: It is easy to perform processing operations such as cutting, bending and polishing.

Electromagnetic properties: It has good electromagnetic properties, so it is also used in the electrical and electronic industries.

3. Classification

According to carbon content: it can be divided into low carbon steel (carbon content is generally less than 0.25%), medium carbon steel (carbon content is generally between 0.25~0.60%) and high carbon steel (carbon content is generally greater than 0.60%). For example, 30CrMnSiA steel plate belongs to medium carbon steel plate.

According to use: it can be divided into structural steel, tool steel and free-cutting structural steel, etc.

According to smelting method: it can be divided into open-hearth steel, converter steel and electric furnace steel, etc.

According to deoxidation method: it can be divided into boiling steel, killed steel, semi-killed steel and special killed steel, etc.

4. Manufacturing process

The manufacturing process of carbon steel plate mainly includes the following steps:

Select suitable raw materials, such as iron ore, alloy elements, etc.

Smelt the raw materials into molten steel, and remove slag and impurities.

Pour the molten steel into the mold and cool it into shape.

Heat treat the formed steel plate to improve its performance.

Carry out cutting, bending, polishing and other processing operations to meet the needs of different fields.

5. Applications

Carbon steel plates are widely used in various fields, including but not limited to:

Automobile manufacturing: used for automobile chassis, body, door, roof and other parts.

Machinery manufacturing: manufacturing various machine tools, punching machines, presses, loaders and other mechanical equipment.

Buildings and bridges: manufacturing steel structures such as bridges, steel buildings, columns, etc.

Shipbuilding: used for the manufacture of ship bottoms, decks, hulls and other parts.

Rail transportation: used to manufacture various components such as tracks, brackets, tunnels, aisles, etc.
