Hot-Rolled Carbon Steel Plate: A Perfect Combination of Corrosion Resistance and Weldability

Hot-rolled carbon steel plate is a type of carbon steel sheet processed through the hot-rolling process.

一、Definition and Production Process

1. Definition: Hot-rolled carbon steel plate is produced by heating the billet to a high temperature (usually above the plastic transition temperature of 1200°C) and then rolling it into the desired shape and size through mechanical force.
2. Production Process: The hot-rolling process includes heating, rough rolling, finish rolling, cooling, and coiling. The billet is heated to a high temperature in a walking-beam furnace, then rolled through roughing and finishing mills, and finally cooled through laminar flow and coiled into hot-rolled steel plate.

二、Characteristics and Advantages

1. High Strength and Toughness: Due to the high-temperature hot-rolling process, the internal structure of hot-rolled carbon steel plate becomes dense with fine grains, giving it high strength and good toughness.
2. Excellent Processability: Hot-rolled carbon steel plates can be easily processed through cutting, welding, bending, punching, and other methods to form various shapes and structures of parts and components.
3. Superior Corrosion Resistance: During manufacturing, hot-rolled carbon steel plate usually undergoes certain surface treatment and coating processes to enhance its corrosion resistance.
4. Good Weldability: The strength and toughness of hot-rolled carbon steel plate can be adjusted as needed. By changing the carbon content and alloy element proportions, different strengths and toughnesses of hot-rolled carbon steel plates can be produced to meet the needs of various fields and applications.
5. Wide Application Adaptability: (Note: This point is repeated; consider merging with the previous "Excellent Corrosion Resistance" point or replacing it with another unique characteristic.) However, it's worth emphasizing again that the adjustable properties make it versatile for numerous applications.
6. Cost-Effective: The production process of hot-rolled carbon steel plate is relatively mature with high production efficiency, and the raw material prices are relatively stable, resulting in high cost-effectiveness.
