Carbon steel coils are coils made by smelting, steelmaking and other processes from iron ore containing a certain amount of carbon elements. Its main components are iron and carbon. The carbon content is generally between 0.05% and 2.0%. The difference in carbon content will affect its mechanical properties and uses.
Classified by production process: mainly divided into hot-rolled carbon steel coils and cold-rolled carbon steel coils. Hot-rolled carbon steel coils are made through a rolling process at high temperatures and have high toughness and plasticity; while cold-rolled carbon steel coils are made through a rolling process at room temperature and have high surface finish and better dimensional accuracy. high.
Classification by use: It can be divided into carbon steel coils for structural use, carbon steel coils for cold forming, carbon steel coils for welding, etc.
The main components of carbon steel coils are carbon and iron, and the content of other alloying elements is relatively low. According to different needs, its properties can be changed by adding appropriate alloying elements, such as adding manganese, chromium, nickel, etc.
ASTM standards: The grades in ASTM standards usually consist of letters and numbers, such as ASTM A36, ASTM A283, etc., among which:
ASTM A36: It is a commonly used structural carbon steel coil, often used in building structures, bridges, vehicle manufacturing and other fields.
ASTM A283: used for general low and medium strength structural steel plates, including A283 Grade A, A283 Grade B, A283 Grade C and other grades.
JIS standards: The grades in JIS standards are usually represented by a combination of letters and numbers, such as SS400, SS490, SS540, etc., among which:
JIS G3101 SS400: A common structural carbon steel coil with good weldability and plasticity, and is widely used in the manufacture of various structural parts.
GB/T standard: The grades in the GB standard usually start with a number, such as Q235, Q345, etc., among which:
GB/T 700 Q235B: It is a common carbon structural steel in Chinese national standards and is suitable for manufacturing various machinery, vehicles, ships and other structural parts.
These grades represent different materials, chemical compositions, mechanical properties and other characteristics. The specific selection should be determined based on specific usage requirements and standard specifications.
application:
Carbon steel coils are widely used in industrial production, mainly including but not limited to the following fields:
Building structure: used to make various steel structures, steel frames, etc.
Automobile manufacturing: used to manufacture automobile bodies, frames and other components.
Machinery manufacturing: used to manufacture mechanical equipment, parts, etc.
Container manufacturing: used to manufacture oil tanks, water tanks and other containers.
Home appliance manufacturing: Used to manufacture casings, parts, etc. of home appliances.
In general, carbon steel coils play an irreplaceable and important role in industrial production due to their low price, excellent processing performance, and wide range of uses.
