Cold rolled low carbon steel is a versatile ferrous metal defined by its low carbon content (typically 0.05%-0.25%) and its processing at room temperature, which compresses and hardens it. This cold rolling results in a material with high strength, precise dimensions, and a very smooth surface ideal for painting and finishing. Its excellent formability and weldability make it the preferred choice for applications requiring a high-quality surface and structural integrity, such as automotive body panels, appliance exteriors, furniture, and various consumer hardware.
Specification Parameters
| Parameters of Cold Rolled Low Carbon Steel | ||
| Parameter Category | Key Characteristics/Values | Notes & Significance |
| Chemical Composition | C (Carbon): Low (0.05% - 0.25%) | The low carbon content is the primary driver for its good weldability and formability. It is typically "killed" (deoxidized with Aluminum) for more uniform properties. |
| Mn (Manganese): 0.25% - 0.60% | ||
| Other Elements: Low levels of Si, P, S. | ||
| Mechanical Properties | Yield Strength (YS): 180 - 300 MPa | Offers a excellent balance of strength and ductility for general forming operations. Higher carbon grades within this range are stronger but less ductile. |
| Tensile Strength (TS): 300 - 410 MPa | ||
| Elongation: 25% - 45% | ||
| Common Grades (Examples) | ASTM A1008: CS (Commercial Steel), DS (Drawing Steel) | Grades are often designated by application (Commercial vs. Drawing quality) or by chemical composition (SAE 10xx series). |
| SAE: 1006, 1008, 1010, 1018 | ||
| EN 10130: DC01, DC03, DC04 | ||
| Key Characteristics | Good Formability: Suitable for bending, moderate drawing, and stamping. | The workhorse grade for general manufacturing. Its properties make it versatile and easy to work with. |
| Excellent Weldability: Can be welded by all common methods. | ||
| Smooth Surface: Ideal for painting and plating. | ||
| Surface Finish | Smooth, uniform matte finish typical of cold-rolled sheet. Available in commercial (CS) or drawing (DS) quality. | The surface is free of mill scale, making it ready for a high-quality finish. Surface quality is suitable for both exposed and unexposed applications. |
| Primary Application | General Forming and Fabrication: | Used where good formability and a quality surface are required, but the extreme ductility of Ultra-Low Carbon steel is not necessary. |
| Automotive non-exposed parts, appliance cabinets, furniture, shelving, hinges, brackets, and general hardware. | ||
