DNV (Det Norske Veritas) is a classification society that sets standards for the maritime industry, including shipbuilding and offshore structures. DNV certifies materials used in these sectors based on specific criteria to ensure safety, quality, and reliability. Some common grades of DNV-approved steel include:

DNV Grade A: This is the most common grade used in general construction and structural applications for ships.

DNV Grade D: Typically used in the construction of ships’ hull structures.

DNV Grade E: Utilized in the fabrication of ship decks and bulkheads.

DNV AH32, DH32, EH32, FH32: These grades are classified as high-strength steels and are used in the construction of offshore platforms.

DNV AH36, DH36, EH36, FH36: High-strength shipbuilding grades used in the construction of ships and marine equipment.

DNV AH40, DH40, EH40, FH40: These are high-strength grades suitable for offshore structures and shipbuilding.

DNV NV A32, NV D32, NV E32, NV F32: Used in the construction of structural parts of ships, barges, and marine equipment.

DNV NV A36, NV D36, NV E36, NV F36: Grades designed for high-strength structural applications in the maritime industry.

These DNV-approved steel grades meet specific requirements for strength, toughness, weldability, and corrosion resistance necessary for marine and offshore applications. Manufacturers and designers adhere to DNV standards to ensure the safety and reliability of structures operating in challenging maritime environments.
