S500Q S550Q High Strength Sheet Metal
S500Q is the German standard high strength structural steel, domestic usually called high strength plate, its composition and performance is equivalent to the national standard Q500D high strength plate, because of its excellent practical performance and is widely used in the construction machinery, mining machinery manufacturing in the use of S500Q because of its excellent practical performance and is used in the construction machinery, mining machinery, coal mining machinery, such as hydraulic brackets, crane extension arm, crane extension arm, excavator support arm, etc.. S500Q low alloy steel material is used in construction machinery, mining machinery, coal mine machinery such as hydraulic support, crane extension arm, crane extension arm, excavator support arm, etc. It is mainly used in the manufacture of hydraulic supports, heavy vehicles, engineering machinery and port machinery with high welding performance.
S550Q high strength low alloy steel is a European standard tempered high yield strength structural steel, S represents structural steel, Q represents the delivery conditions, 550 is the yield value, unit MPa, can be divided into: S550Q, S550QL, S550QL1. S550Q steel is a grade in the EN 10025-6 standard, the standard specifies that the minimum nominal thickness of the steel is 3mm, the maximum nominal thickness ≤ 150mm. S550Q high strength low alloy steel plate is adapted to electric power towers, all kinds of lifting cranes, heavy vehicles, oil derricks, high temperature fans, large electric shovels, dump trucks and drilling rigs, hydraulic supports for coal mines, steel structures and so on.
