S550QL1 High Tensile Steel Sheet
S550QL1 is a special alloy steel, the European standard plate number is divided into S550Q, S550QL, S550QL1; S550QL1 steel plate belongs to the tempered high yield strength structural steel, S indicates structural steel, 550 is the yield value, unit MPa, Q indicates the delivery conditions, L1 indicates that the temperature is not less than -60 ° C when the impact of the work of the specified minimum value. s550QL1 steel plate is usually often Used in the construction of machinery and high-strength structural components used. Corresponding to the national standard material steel number is generally Q550F, impact temperature of -60 degrees, can be used in extremely cold conditions.
