Mechanical properties and fatigue resistance of S890QL

The composition of S890QL steel plate mainly includes basic elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and micro-alloying elements such as chromium (Cr), nickel (Ni), Copper (Cu), molybdenum (Mo), nitrogen (N), titanium (Ti), vanadium (V), etc. In addition, aluminum (Al) is also one of the elements, and its content should reach at least 0.015% to refine the grains. The specific contents of these elements vary according to the production standards and performance requirements of the steel plate.

S890QL steel plate has a wide range of applications, mainly due to its excellent properties such as high strength, high toughness, fatigue resistance and impact resistance. This steel plate performs well when withstanding large loads and complex stresses, making it particularly suitable for use in the following areas:

Bridge engineering: The high strength characteristics of S890QL steel plate enable it to withstand the huge stress and load that may occur during the operation of the bridge structure, ensuring the safety and stability of the bridge.
Construction engineering: In the field of construction, S890QL steel plates are often used in key parts of structures such as high-rise buildings and large public facilities, such as columns, beams, nodes, etc., to enhance the load-bearing capacity and seismic performance of the overall structure.
Ship manufacturing: Since ships need to operate in various harsh sea conditions, the requirements for materials are extremely high. The high strength and impact resistance of S890QL steel plates make it an ideal choice for shipbuilding, especially for critical parts such as hulls, bottoms and bridges.
Mechanical Engineering: In the field of mechanical engineering, S890QL steel plates are widely used in the manufacture of key components of various heavy machinery such as excavators, loaders, and cranes, such as booms, chassis, crawlers, etc., to improve the performance and durability of the machinery.
In addition, S890QL steel plate is also suitable for wear-resistant mining machinery industry and mechanical engineering applications requiring high strength. These fields have equally stringent requirements for materials, requiring materials to have excellent mechanical properties and fatigue resistance.
