High-Strength Plate Applications High-strength plates, also known as high-strength steel plates, low-alloy high-strength plates, and high-strength welding plates, are characterized by their high strength and yield points. They are broadly categorized into: Q390, Q420, Q460, Q500, Q550, and Q690. Different steel mills have varying factory standards, such as Ansteel's AH60, which is also called Q460, and Wuhan Iron and Steel's WH HG60, all of which possess the same performance but different names. High-strength plate AH60, Q460: This product is widely used in various construction machinery, such as drilling machines, electric shovels, electric wheel loaders, mining vehicles, excavators, loaders, bulldozers, cranes, and hydraulic supports for coal mines, among other equipment and structural components. High-strength plates are generally categorized into: Q390, Q420, Q460, Q500, Q550, and Q690. Different steel mills have varying factory standards, such as Ansteel's AH60 and Wuhan Iron and Steel's WH HG60, all of which offer the same performance but differ in naming. When it comes to pricing, there's a wide range due to regional and temporal variations. The current market price determines the classification of the plates.
