CCS AH40 DH40 EH40 FH40 Marine Steel Plate

CCSAH40 steel is a kind of hot rolled high tensile strength steel.
Higher-strength CCS shipbuilding steel comes in 12 grades of 3
strengths, AH40 is one of the grades. The CCS AH40 grade steel
plates have yield strength of 56,500 psi (390 MPa), and ultimate
tensile strength of 74,000 - 94,500 psi (510-650 MPa).



Product

Brief introduction of marine steel plate
Marine steel plate refers to structural steel used in ship building. It is considered a marine grade and must be able to resist corrosive effects that are common in a water environment. To achieve this, special alloying elements are added to these grades in order to defend agaist corrosion.While most carbon steel is not suited for marine environments, there are several marine grade carbon steels that have been approved by the different societies for shipbuilding applications.

Structural steel for ship hulls is divided into strength classes according to its minimum yield strength: general strength structural steel and high strength structural steel. Maine steel plate refers to hot rolled steel plate produced in accordance with the requirements of the classication society for the construction of ship hull structures.

There are 9 main classification societies in worldwide.

D.N.V   Det Norske Veritas
G.L.    Germanischer Lloyd

CCSAH40 steel is a kind of hot rolled high tensile strength steel. Higher-strength CCS shipbuilding steel comes in 12 grades of 3 strengths, AH40 is one of the grades. The CCS AH40 grade steel plates have yield strength of 56,500 psi (390 MPa), and ultimate tensile strength of 74,000 - 94,500 psi (510-650 MPa).

CCS is a founding member of the International Association of Classification Societies(IACS),formed in 1968. The CCS fleet is recognized by approximately 116 international flag authorities. CCS integrated services for the complate shipping cycle including design, building, shipyard management, inspection and testing of materials/components and regular inspections to maintain the class are used by freight, ferries, ro-ro, passenger ships, yachts, cruise ships, navy, LGN and other specialist carrier vessels.

Grade AH40 steel is the impact force subjected to 0 ° C
Grade DH40 steel impact force at  -20 ° C
Grade EH40 steel impact force at -40 ° C
Grade FH40 steel impact force at -60 ° C

Shot blasting service
Shot blasting is a method used to clean or polish steel when enhanced surface finishes are required. Shot blasting is used in almost every industry we serve. Especially in shipbuilding, rail,structural fabrication and more.

Processing for Different Grades
Grade D, E (DH32, DH36, EH 32, EH 36)
Grade D and E series (inlcuding AH32/36, DH32, DH36, EH32, EH36) shipbuilding steel plates require good low temperature toughness and good welding performance. The production high-strength shipbuilding steel plate needs to be normalized by means of controlled rolling and controlled cooling or heat treatment processes with more complete equipment. At the same time, the internal steel purity of the supplied billets is required to be high, especially the content of S, P, N, 0 and H in the steel should be strictly controlled.

Alloy Elements Added to Improve Toughness
In order to ensure the performance of high-strength ship plates, micro-alloying technology is adopted. By adding Nb, V, Ti and other alloying elements to the steel, combined with the controlled rolling process, the grain is refined and the toughness is improved.
Direction of Development for Shipbuilding Plate
High strength, high specification, with the ship's large-scale and safety, and changes in coating specifications, the demand for ordinary A-class panels is gradually reduced, and the demand for high-strength panels is increasing, which is concentrated in large ships of 5m wide. Plate, 200-300mm thickness special thick ship board.
