Introduction to Q390D

First, Q390D steel plate is a low-alloy high-strength steel plate, the implementation of GB/T1591 standard. The same level is Q390A, Q390B, Q390D, Q390E. Q390D steel plate has high strength, good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. High strength, especially in the state of normalizing or normalizing plus tempering has high comprehensive mechanical properties.

Second, Q390D composition and performance
