Q390C angle steel is a high-strength low-alloy structural steel commonly used in the manufacturing of structural components that bear high loads. The forming process of this angle steel typically involves hot rolling or cold rolling. Hot-rolled angle steel is formed at high temperatures, which allows for better plasticity and toughness, making it suitable for the production of large structural components. In contrast, cold-rolled angle steel is formed at room temperature, offering higher dimensional accuracy and surface smoothness, though it may require greater forming force.

During the forming process of Q390C angle steel, temperature and pressure must be strictly controlled to ensure the material's mechanical properties remain unaffected. After forming, the angle steel usually undergoes heat treatment, such as normalizing or annealing, to eliminate internal stress, improve the microstructure, and enhance the material's toughness and stability. Additionally, Q390C angle steel exhibits good weldability, making it suitable for various welding processes and facilitating on-site assembly during construction.

Due to its high strength and excellent processing performance, Q390C angle steel is widely used in fields such as construction, bridges, machinery manufacturing, and vehicle manufacturing, especially in applications requiring high load-bearing capacity and resistance to complex stresses.
