S500QL S550QL HSLA Structural Steel
S500QL is a European standard high strength structural steel, usually called high strength plate in China, its composition and properties are equivalent to the national standard Q500D high strength plate, which is widely used in the manufacture of construction machinery and mining machinery because of its excellent practical performance.
S550QL belongs to the European standard low alloy high-strength structural steel plate, S550QL high strength low alloy steel plate implementation standard: EN10025 .S550QL low alloy steel plate is widely used by the manufacturing industry because the steel plate itself has a variety of high-quality performance, in the use of the process of high-quality performance of the display has been unanimously praised and recognised by the manufacturing industry, the latter because of social recognition of the manufacturing industry's extensive use and manufacturers continue to optimize the material upgraded, and gradually the S550QL high strength steel plate has become the commonly used in the domestic steel plate one of the grades.
