Q345NH weathering steel plate

Q345NH weathering steel plate is a low-alloy high-strength weathering steel. It improves the atmospheric corrosion resistance of steel by adding a small amount of copper, phosphorus, chromium, nickel and other alloy elements to ordinary carbon steel. The grade of this steel is composed of "yield strength", the first letters of the Chinese pinyin of "weathering resistance" "Q" and "NH" and the lower limit of yield strength. "345" means that its yield strength is 345 MPa.
