CCS AH32 marine steel plate purity requirements. CCS AH32 marine steel plate need to have very low P, S and other impurity elements content, and have high requirements for the morphology, type and distribution of inclusions to avoid fatigue failure of offshore platforms when affected by typhoon and water movement.
CCS AH32 marine steel plate requirements for corrosion resistance of marine steel plates. Because marine steel structures are exposed to salt spray, moisture, and sea water for a long time, they are subject to severe electrochemical corrosion due to the erosion of sea water and marine organisms, and the paint film is prone to severe saponification and aging, resulting in very serious structural corrosion.
It not only reduces the mechanical properties of CCS AH32 marine steel plate and shortens its service life, but also because it is far from the coast, it cannot be repaired and maintained regularly like ships. Therefore, the requirements for corrosion resistance of CCS AH32 marine steel plate are higher.
