S355J2G3 Q345R C Channel Beam

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
