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.

PRODUCT DETAILS

Performance characteristics: Excellent atmospheric corrosion resistance: By adding copper (Cu), chromium (Cr), nickel (Ni) and other elements, a stable rust layer can be formed in the atmospheric environment, effectively preventing further corrosion.
Good comprehensive mechanical properties: It has both high strength and certain toughness.
Application areas: Widely used in the manufacture of steel structures such as railway vehicles, bridges, and ships. These structures are exposed to the atmospheric environment for a long time and need to have good corrosion resistance.
Can be used for building structures such as large factories, stadiums, etc. It is also used in the production of containers and special vehicles.
