DNV D grade: Usually used in the construction of ship hull structures.
DNV Grade E: Used for the manufacture of ship decks and bulkheads.
DNV AH32, DH32, EH32, FH32: These grades are categorized as high-strength steels and are used in the construction of offshore platforms.
DNV AH36, DH36, EH36, FH36: high-strength shipbuilding steels for the construction of ships and marine equipment.
DNV AH40, DH40, EH40, FH40: high-strength grades for offshore structures and shipbuilding.
DNV NV A32, NV D32, NV E32, NV F32: Structural components for the construction of ships, barges and marine equipment.
DNV NV A36, NV D36, NV E36, NV F36: grades designed for high-strength structural applications in the marine industry.
