Carbon steel plate is an alloy material with iron and carbon as its main components, and its properties are primarily determined by its carbon content. The following are its core characteristics:
Mechanical Properties:
Tensile Strength: Low-carbon steel (e.g., Q235) has a tensile strength of 370-500 MPa, while high-carbon steel (e.g., C70) can reach over 800 MPa (refer to GB/T 700-2006).
Dulleriness: The lower the carbon content, the better the ductility. For example, the elongation after fracture of low-carbon steel can reach over 25%.
Corrosion Resistance: Ordinary carbon steel plates are prone to rust and require processes such as galvanizing and painting to improve their protective properties.
Weldability and Machinability: Low-carbon steel has excellent weldability, while high-carbon steel requires preheating to avoid cracking.
