Q345E is a grade of high strength low alloy structural steel. It is a low-carbon non-alloy structural steel with good cold forming property and welding performance. Q345E steel can be used in the manufacture of engineering structures, such as automobiles, ships, bridges, oil tanks, containers, railway wagons, hoisting machinery, etc. It can also be used in steel construction, bridge and large-diameter pipelines, and can also be used as the material for large-scale rigid components and seat frames.
Q345E steel is usually supplied in quenched and tempered condition. Under this condition, the steel not only has good strength, but also has good plasticity and toughness. The weldability and machinability have been improved compared with the normal low alloy structural steel. In addition, it also has better cold forming performance, and its low temperature toughness, impact energy and other mechanical properties can also be tested.
Q345E plate can be used in engineering structures such as towers and bridges, it can also be used as bridge plates, pre-stressed components, and other structures requiring superior mechanical properties, such as large-scale frames and rigs. In addition, it can be applied in the production of large mechanical containers in the form of beams and columns.
Q345E steel is also used in the manufacture of vessel parts, such as bilge plates, deck plates, bilge plates, deck plates, and so on. The steel has good welding performance and can be used to manufacture various types of welded structures, such as pressure vessels, heat exchangers and so on. This steel has good wear resistance and can be used to manufacture wear-resistant and wear-resistant structural components for various industries.
Q345E steel can also be used in the field of shipbuilding. It is also applied in the production and production of fuel tanks, oil tanks, petrochemical plant equipment and other large-scale containers. At the same time, this steel can also be used in the production of crane and hoist. The steel can bear tensile and other loads in the crane and hoisting machinery and is therefore widely used in this field.
In summary, Q345E is a grade of high strength low alloy structural steel, which is usually supplied in quenched and tempered condition. It has good weldability, machinability and cold forming performance, and is mainly used in engineering structures such as automobiles, ships, bridges, oil tanks, containers, lifting machinery and steel construction. In addition, it can also be used to produce large-scale mechanical containers, vessel parts, fuel tanks, car lift and hoist components and other large-scale containers.
