Why choose the Q355NH steel plate

The corrosion resistance of Q355NH steel plate is obviously better than Q345B steel plate, which is equivalent to ASTM A588 Gr A steel plate.
Q355NH steel plate and ASTM A588 Gr A steel both contain copper, chromium, nickel and other alloying elements. The good corrosion resistance of the alloy cannot be separated from these alloy elements and the rust layer structure.

Q355NH steel plate mechanical properties meet technical requirements. Q355NH steel plate has high strength, low thickness effect, excellent low temperature impact performance and excellent welded joint performance.
