DNV Grade E420 steel plate is mainly used to building ships,so we also call this steel as DNV Grade E420 ship plate,DNV E420 shipbuilding steel plate,DNV E420 marine steel plate or NV E420 shipbuilding plate.Anyway these DNV E420 plates are the same and owned higher steel strength at minimum yield strength 420 Mpa and with minimum tensile strength 530 Mpa.Done low temperature impacting test for DNV E420 under 40 centigree when rolling.
