Hot Rolled Mild Carbon Steel Sheet Plate in Coil Hot rolled mild carbon steel sheet plate in coil is a widely used industrial material known for its versatility, strength, and cost-effectiveness. It is produced through a hot rolling process, where steel slabs are heated above their recrystallization temperature (typically around 1,100°C to 1,300°C) and passed through a series of rollers to achieve the desired thickness and dimensions. This method ensures excellent formability, weldability, and machinability, making it suitable for various applications across multiple industries. Key Characteristics 1. Material Composition: Mild carbon steel contains a low percentage of carbon (usually 0.05% to 0.25%) along with small amounts of manganese, phosphorus, sulfur, and silicon. This composition provides a balance of ductility and strength, making it easy to shape while maintaining structural integrity. 2. Surface Finish: The hot rolling process results in a slightly rough, scaled surface, which can be further treated (e.g., pickling, oiling, or galvanizing) for improved corrosion resistance or aesthetics. 3. Mechanical Properties: Hot rolled mild carbon steel exhibits good tensile strength (typically 370-500 MPa) and elongation properties, allowing it to withstand bending, stamping, and forming without cracking. 4. Dimensional Range: Available in various thicknesses (usually 1.2mm to 20mm) and widths (up to 2,000mm), the steel is supplied in coil form for efficient storage, transportation, and processing. Applications Due to its adaptability, hot rolled mild carbon steel coil is used in: - Automotive Industry: Structural components, chassis parts, and body panels. - Construction: Beams, frames, roofing, and reinforcing elements. - Manufacturing: Pipes, tubes, storage tanks, and machinery parts. - General Fabrication: Metal furniture, agricultural equipment, and enclosures. Advantages - Cost-Effective: Lower production costs compared to cold-rolled steel. - High Workability: Easily welded, cut, and formed into complex shapes. - Durability: Suitable for heavy-duty applications requiring moderate strength. Considerations While hot rolled steel offers many benefits, it is less precise in dimensions than cold-rolled steel and may require additional surface treatment for corrosion-prone environments. In summary, hot rolled mild carbon steel sheet plate in coil is a fundamental material in modern industry, valued for its strength, flexibility, and affordability. Its widespread use underscores its importance in manufacturing, construction, and engineering applications.
