Products Description
Cold rolled steel plate plays a crucial role in modern manufacturing, especially in industries that demand high surface quality, tight dimensional tolerance, and stable mechanical performance. Among the most widely used cold rolled steel grades, DC01, DC03, DC04, DC05, DC06, and DC07 defined under EN 10130 are commonly selected for applications ranging from basic structural components to complex deep-drawing parts.
Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.
Cold rolled steel
What Is Cold Rolled Steel Plate?
Cold rolled steel plate is produced by further processing hot rolled steel through cold reduction at room temperature. This process significantly improves surface finish, thickness accuracy, and mechanical consistency. Compared with hot rolled steel, cold rolled grades offer smoother surfaces, better flatness, and enhanced formability, making them ideal for precision stamping, bending, and forming operations.
Types of carbon steel and their properties
Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:
| Carbon content (wt.%) | Microstructure | Properties | Examples |
| Low-carbon steel | < 0.25 | Ferrite, pearlite | Low hardness and cost. High ductility, toughness, machinability and weldability |
| Medium-carbon steel | 0.25 – 0.60 | Martensite | Low hardenability, medium strength, ductility and toughness |
| High-carbon steel | 0.60 – 1.25 | Pearlite | High hardness, strength, low ductility |
