LR Grade AH32 DH32 EH32 FH32 Marine Steel Plate

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.
Brief introduction of marine steel plate
LR FH32 steel is a kind of hot rolled high tensile strength steel. Higher-strength LR shipbuilding steel comes in 12 grades of 3 strengths, FH32 is one of the grades. The LR FH32 grade steel plates have yield strength of 315 MPa), and ultimate tensile strength of 440-570 MPa. All the LRFH32 shipbuilding Steel offered by Gnee can be certificated by Lloyd’s Register of Shipping (LR).

Grade AH32 steel is the impact force subjected to 0 ° C
Grade DH32 steel impact force at  -20 ° C
Grade EH32 steel impact force at -40 ° C
Grade FH32 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.
