Alloy steel hardox 450 chemical composition supply

Although Q345E steel plate has stronger torsion resistance and better corrosion resistance than ordinary steel plate, there are still some environments that can cause corrosion to Q345E steel plate. The following environment should be avoided as far as possible to avoid corrosion of , Q345E steel plate. 1. Acid water. 2. Salt water. 3. Nitric acid. 4. Atmospheric erosion. Atmospheric erosion for Q345E steel plate corrosion is reflected in the chloride and pollutant pollution source of Q345E steel plate corrosion, this corrosion is very serious.
