Carbon Steel Bar
HIGH QUALITY PRODUCTS
Carbon Steel Bar
Melting and Casting: Carbon steel is produced by melting iron with carbon and other elements in a furnace. The molten steel is then cast into billets or ingots.
Hot Rolling: The billets are heated and passed through rolling mills to reduce their thickness and shape them into bars. This process can create different cross-sectional shapes like round, square, hexagonal, and flat bars.
Cooling: The hot-rolled bars are then cooled, either in air or through controlled cooling methods to achieve desired properties.
Finishing: The bars may undergo additional finishing processes like straightening, cutting, and surface treatment to meet specific requirements.

Typical Chemistry:
The chemical composition of carbon steel bars varies based on the specific grade. A common example is the AISI 1018 carbon steel:
- Carbon (C): 0.15% to 0.20%
- Manganese (Mn): 0.60% to 0.90%
- Phosphorus (P): ≤ 0.040%
- Sulfur (S): ≤ 0.050%
Other grades, such as 1045, 1020, and 1095, have different compositions tailored to specific applications, providing varying levels of hardness, strength, and ductility.
Physical Properties:
The physical properties of carbon steel bars depend on the specific grade and processing methods, but typical properties include:
- Tensile Strength: Ranges from 400 MPa to 850 MPa.
- Yield Strength: Generally between 250 MPa and 600 MPa.
- Elongation: Typically between 10% and 25%, indicating varying ductility.
- Hardness: Varies depending on the grade and heat treatment, typically between 120 to 200 HB (Brinell hardness).
- Density: Approximately 7.85 g/cm³.
- Melting Point: Around 1425°C to 1540°C.
- Thermal Conductivity: Approximately 51.9 W/m·K.
- Electrical Resistivity: Approximately 0.0000159 Ω·cm.
