Q390B/Q390C/Q390D low alloy high strength plate cutting

Q390B/Q390C/Q390D are low-alloy high-strength steel plates, the difference lies in the impact temperature of the steel plates. The similarities between Q390B and Q345B belong to carbon structural steel, and the quality grade is B. The difference is that Q390 indicates that the yield point (σs) is 390 MPa, and Q345 indicates that the yield point (σs) is 345 MPa, and the latter has stronger resistance to deformation.

Q390B is stronger than Q345B and is a kind of structural steel.

Q390B/Q390C/Q390D low alloy high strength plate mechanical properties:
