Based on the factory's test data on steel plates before delivery, the GB/T 591 standard provides comprehensive data tables for the chemical composition and mechanical properties of Q390, Q420, Q460, Q500, Q550, Q620, and Q690 steel grades.

GB/T 1591 Low alloy Carbon Steel Plate, its grades are such as Q355, Q390, Q420, Q460, Q500, Q550, Q620 and Q690. These grades of steel plates are widely used in deep processing such as welding, cutting and forming.

Low alloy carbon plate is widely used because of its high strength and balanced carbon content, which makes it suitable for welding. It is most commonly used in construction and heavy machinery. Cutting processes (including plasma cutting and laser cutting) are common because the composition of the material allows for clean and precise cuts. Forming operations such as bending and stamping are widely used because of its good ductility and elongation, allowing complex shapes to be created without compromising structural integrity.

GB/T 1591 low alloy carbon steel plates are mainly used in the building structures, bridges and heavy machinery industries. Due to their high strength and durability, they are also used to make pressure vessels, industrial frames, and parts for cranes and other heavy equipment.
