CCS AH40 marine steel plate is mainly used to build ships, so we also call it CCS Grade AH40 ship plate, CCS grade AH40 shipbuilding steel plate, CCS AH40 marine steel plate or CCS grade AH40 shipbuilding steel plate. In short, these CCS AH40 marine steel plate are the same. At least have a high steel strength yield strength of 390mpa, the minimum tensile strength of 510MPa. Low temperature impact test on CCS AH40 marine steel plate at zero degrees Celsius during rolling.
