S355J2G3 Q345R Steel Angle

S355J2G3 is a European standard steel, the composition is: C ≤0.20, Si≤0.55, Mn ≤1.60, P≤0.035, S≤0.035. The beginning of S is structural steel, 355 means that the minimum yield strength is 355MPa. J2G3 means that the delivery state is normalized, the impact work of -20℃ is 27J, G3 and G4 are the meaning of the characterization of deoxidation mode. S355J2G3 indicates semi-killed steel. Q355D is a low-alloy high-strength steel plate, which is often used in the machinery manufacturing industry For example; Crane, hydraulic press, construction machinery, heavy machinery, bridge structure, head, mechanical parts, steel structure, large forklift, agricultural machinery, etc

1.Products Description

S355J2G3 low-alloy steel is produced in accordance with European standards, which is slightly higher than the Q345 series steel plate in domestic GB/T1591-1994, and is widely used in the railway vehicle manufacturing industry.

The chemical composition of S355J2G3 steel is C≤0.20, Si≤0.55, Mn≤1.60, P≤0.035, S≤0.035. Deoxygenation method FF.

In the alternation of dry and wet environments, a-FeOOH can buffer the volume change between the rust particles, reduce the thermal stress between the rust layer and the substrate, improve the adhesion of the rust layer, and thus protect the oxide film. Increase, the corrosion resistance of steel is improved.

At the same time, compared with the Q345R steel, the Cr content in the S355J2G3 steel is higher, and Cr has a significant effect on improving the passivation ability of the steel. As a result, the corrosion resistance of the welded joint of S355J2G3 steel is better than that of Q345R steel.
