Hot Rolled Carbon Steel Coil

Low carbon steel plate: For carbon content 0.06% to 0.25%, also we call it mild steel plate. Medium carbon steel plate: C content from 0.25% to 0.55%. High carbon steel plate: 0.55% to 1.0%, also called hard steel plate. As the content of Carbon increase, the steel plate hardness increases.Carbon hot rolled steel sheets and plates are used in the welding and construction sectors such as railroad tracks, construction equipment, boom cranes, agriculture equipment and heavy vehicle frames. By varying the percentage in carbon steel, it is possible to produce steel with a variety of different qualities. In general, higher carbon content in steel makes steel harder, brittler and less ductile.

Advantages of hot rolled coil:

1. It has a high strength-to-weight ratio, making it ideal for construction and shipbuilding.

2. Highly resistant to corrosion and wear, very suitable for pressure vessels and piping systems.

3. It has excellent weldability and formability, making it suitable for various manufacturing processes.
