Carbon Structural Steel, it is a kind of carbon steel. The carbon content is about 0.05% ~ 0.70%, some may be as high as 0.90%. It can be divided into ordinary carbon structural steel and high quality carbon structural steel. Mainly used for railway, bridge, all kinds of construction engineering, the manufacture of various metal components bearing static load and mechanical parts and general welding parts which are not important and do not need heat treatment.
Differences Between Cold Rolled Steel Coils and Hot Rolled Steel Coils
1. Production Process:
- Hot Rolled Steel Coils: These are produced by heating steel above its recrystallization temperature (over 1700°F or 926°C) and then rolling it into sheets or coils. The process allows the steel to be easily shaped and formed.
- Cold Rolled Steel Coils: After hot rolling, the steel is further processed at room temperature through cold reduction. This process increases its strength and improves its surface finish.
2. Surface Finish:
- Hot Rolled Steel Coils: The surface is typically rougher due to the scale that forms on the steel during cooling. The finish is less smooth, which might require additional processing if a finer finish is needed.
- Cold Rolled Steel Coils: These coils have a smoother, more polished surface, which makes them ideal for applications requiring a high-quality surface finish.
3. Dimensional Accuracy:
- Hot Rolled Steel Coils: The process involves less precision, leading to variations in thickness and shape. This is often suitable for applications where these variations are acceptable.
- Cold Rolled Steel Coils: These are produced with greater precision, resulting in tighter tolerances and more consistent thickness, which is critical for high-precision applications.
4. Strength and Hardness:
- Hot Rolled Steel Coils: The steel is more ductile but less strong, making it easier to work with in forming and shaping processes.
- Cold Rolled Steel Coils: The cold rolling process hardens the steel, increasing its strength and hardness, which is beneficial for structural applications.
5. Applications:
- Hot Rolled Steel Coils: Commonly used in applications like construction (e.g., I-beams), rail tracks, and heavy machinery where surface finish and precision are less critical.
- Cold Rolled Steel Coils: Preferred in applications requiring a high degree of precision and smooth surface finish, such as automotive parts, appliances, and metal furniture.
At present, the main grades include two parts: re-rolling grades, Q215B and SPHC for domestic, SPHT1,SPHC(B),DD11,HR 235(B),SAE1006,SAE1008 for export; Structural grade, Q235B for domestic, S235JRB,SPHT2,A36B,SS400B for export. The advantages of ESP hot-rolled products are thin gauge, high dimensional accuracy, excellent processing performance and high yield.
