Flame cutting of S460QL material
How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, S460QL material, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ~ 0.75, Mn: 0.20 ~ 0.50, P: 0.07 ~ 0.15, S≤0.03, Cu: 0.25 ~ 0.55 , Cr: 0.30 ~ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet S460QL material is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate S460QL material after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development.
