High strength structural steel S500Q plate

S500Q steel plate is used in construction machinery, mining machinery and coal mining machinery, such as hydraulic support, crane extension arm, crane extension arm, excavator support arm, etc. High strength structural steel S500Q plate is mainly used for manufacturing hydraulic supports, heavy vehicles, engineering machinery and port machinery with high welding performance.

S500Q structural steel plate standard: EN 10025-6
Heat treatment: quenching and tempering

Chemical composition of S500Q plate:
The quality of S500Q is divided into three levels:
S500Q: P: ≤ 0.025, S: ≤ 0.015;
S500QL: P: ≤ 0.020, S: ≤ 0.010;
S500QL1: P: ≤ 0.020, S: ≤ 0.010;
Other ingredients are the same, as follows:
C:≤0.20, Si:≤0.80, Mn:≤1.70, N:≤0.015, B:≤0.0050, Cr:≤1.50, Cu:0.50, Mo:0.70, Nb:0.06, Ni:≤2.0, Ti:≤0.05, V:≤0.12, Zr:≤0.15

S500Q and S500QL steel plates are high strength structural steels, which are generally called high-strength plates, equivalent to the national standard Q500D, and are widely used in construction machinery and mining machinery.
