As the main material of ship construction, DNV GL DH32 steel plate has strict quality requirements. Both fresh water and ships sailing on the sea are in direct contact with water, which will be electrolyzed by water and decomposed by microorganisms in water.
At the same time, DNV GL DH32 steel plate will also be impacted by big waves. This requires not only the corrosion resistance of ship plate, but also the anti impact ability. Therefore, DNV GL DH32 steel plate needs to have good comprehensive performance.
It can meet the requirements of general mechanical and cold rolling process for DNV GL DH32 steel plate, which can meet the requirements of general mechanical and cold rolling process. At the same time, the internal steel purity of the billets is required to be high, especially the contents of S, P, N, 0, H in DNV GL DH32 steel plate should be strictly controlled.
