Carbon steel plate/carbon steel sheet is a flat material made of carbon steel, which is widely used in many industries such as construction, manufacturing, automobile, energy, machinery, etc. Carbon steel is an alloy mainly composed of iron and carbon. According to the different carbon content, carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Carbon steel plates are usually made by rolling, shearing, laser cutting, etc., and have good strength, hardness, weldability and machinability.
Material and classification
The properties of carbon steel depend on its carbon content. Common classifications include:
Low carbon steel (also called mild steel):
The carbon content is usually less than 0.3%. It has high plasticity and low strength, and is widely used in the manufacture of structural parts, pipes, automotive parts, etc.
Medium carbon steel:
The carbon content is usually between 0.3% and 0.6%. It has high strength and hardness and is suitable for the manufacture of mechanical parts, automotive parts, drive shafts, gears, etc.
High carbon steel:
The carbon content is usually higher than 0.6%. High carbon steel has high hardness and wear resistance and is often used in the manufacture of tools, knives, springs, etc.
Processing and surface treatment of carbon steel plates
Carbon steel plates usually need to be processed and surface treated to improve their performance and adapt to different application requirements. Common processing methods include:
Cutting: Cut the carbon steel plate by laser cutting, plasma cutting, flame cutting, etc. to obtain the required shape and size.
Stamping and forming: Use stamping dies or presses to form carbon steel plates to manufacture complex parts.
Welding: Carbon steel plates have good weldability and can be connected into different structures by arc welding, gas welding, laser welding, etc.
Bending and folding: Bend carbon steel plates by hydraulic presses, bending machines and other equipment to make parts of different shapes.
Heat treatment: Through annealing, normalizing, quenching, tempering and other processes, adjust the hardness, strength and toughness of carbon steel plates to adapt to different working environments.
Surface treatment:
Pickling: Remove the oxide scale and impurities on the surface of the steel plate to make the surface smooth and clean.
Coating: Carbon steel plates are coated, such as painting, galvanizing, chrome plating, etc., to improve their corrosion resistance.
Rust prevention: Through coating or oil seal treatment, carbon steel plates can be prevented from rusting and their service life can be extended.
Advantages of carbon steel plates
High strength and toughness:
Carbon steel plates have high strength and good impact resistance, and are suitable for load-bearing structures.
Good processing performance:
Carbon steel plates are easy to process and form, and are suitable for manufacturing in different shapes and sizes.
Economical:
Compared with other alloy steels, carbon steel is relatively cheap and suitable for large-scale production and universal application.
Wide range of weldability:
Carbon steel plates have good weldability and can be connected by a variety of welding methods.
Good wear resistance:
Especially high carbon steel, which can provide strong wear resistance and is suitable for high-intensity working environments.
Application areas of carbon steel plates
Carbon steel plates have high strength, toughness, good weldability and processing properties, and are widely used in many industries:
Construction industry:
used for steel beams, steel columns, steel plates, steel pipes, etc. in building structures, especially for large structures and load-bearing parts.
Automobile industry:
used to manufacture automobile bodies, chassis, engine parts, wheels, automobile parts, etc., because of its light weight and moderate strength, it can improve the durability of automobiles.
Mechanical manufacturing:
Carbon steel plates are used to produce various mechanical parts, tool racks, equipment housings, etc.
Oil and gas industry:
Carbon steel plates are used to manufacture pressure vessels, pipelines, storage tanks and other equipment, especially low-carbon steel is used for delivery pipelines.
Shipbuilding:
Used in the manufacture of hull structures and ship parts, especially medium-carbon steel and low-carbon steel are widely used in shipbuilding.
Energy industry:
Used in key components in energy facilities such as nuclear power and thermal power plants, such as boilers, heat exchangers and other equipment.
Home appliance industry:
For example, refrigerators, washing machine housings and parts.
