Carbon Steel Coil
Carbon steel coil is a coiled material made of carbon steel, mainly produced by hot rolling or cold rolling process. Carbon steel is an iron-carbon alloy, the carbon content is usually between 0.05% and 2.0%, and may also contain small amounts of other elements such as manganese, silicon, etc.
Description
Carbon steel coil is a coiled material made of carbon steel, which is mainly produced by hot rolling or cold rolling process. Carbon steel is an iron-carbon alloy with a carbon content usually between 0.05% and 2.0%, and may also contain small amounts of other elements such as manganese, silicon, etc.
Classification
By carbon content:
Low carbon steel (carbon content ≤ 0.25%)
Medium carbon steel (carbon content 0.25%-0.60%)
High carbon steel (carbon content ≥ 0.60%)
By production process:
Hot rolled carbon steel coil
Cold rolled carbon steel coil
By use:
Carbon steel coil for structure
Carbon steel coil for stamping
Carbon steel coil for deep drawing
Process
Hot rolling process: The steel billet is heated to a high temperature and then rolled and coiled into a coil.
Features: High production efficiency, oxide scale on the surface, and low dimensional accuracy.
Cold rolling process:
After the hot rolled coil is pickled to remove the oxide scale, it is rolled and coiled at room temperature.
Features: Smooth surface, high dimensional accuracy, and good mechanical properties.
Features
Mechanical properties:
Strength and hardness increase with increasing carbon content, but plasticity and toughness decrease.
Processing performance:
Low carbon steel is easy to process and weld, while high carbon steel is more difficult.
Surface quality:
The surface of hot-rolled coil has oxide scale, while the surface of cold-rolled coil is smooth.
Cost:
Carbon steel coil has low cost and is suitable for large-scale application.
Use
Construction industry:
Used for steel structures, bridges, building frames, etc.
Automobile manufacturing:
Used for car bodies, chassis, doors and other parts.
Home appliance manufacturing:
Used for housings and structural parts such as refrigerators and washing machines.
Machinery manufacturing:
Used for manufacturing parts such as gears, shafts, bolts, etc.
Packaging industry:
Used for manufacturing metal packaging containers, barrels, etc.
Carbon steel coils are widely used in construction, automobiles, home appliances, machinery and packaging industries due to their good mechanical properties, processing performance and low cost. According to the carbon content and production process, carbon steel coils can be divided into many types, each with its own characteristics and applicable fields.
