EN10025-3 S460N high-strength steel has high strength, especially in normalizing or normalizing and tempering state. It has higher comprehensive mechanical properties. S460N plates are mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. S460N mechanical properties: tensile strength Rm500-680MPa, yield strength: 420-320MPa, elongation after fracture 18-19%.

Spring steel has good fatigue strength and can be restored to its original state after repeated use, without deformation, because the spring has good ductility and can be changed back to the original state no matter how long it is stretched. 5mm thickness EN1522 FB6 steel, Spring steel has good elasticity. Spring steel can not only be made into springs, but also be processed into swords, which requires good elasticity. The tensile strength of spring steel is good, it will not break and can be recovered under the condition of tensile limit.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of 5mm thickness EN1522 FB6 steel, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

5mm thickness EN1522 FB6 steel, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.
