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.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
