PRODUCT DETAILS

Brief introduction of marine steel plate AH/DH/EH32
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. The general strength steel s of the China Classification Society are divided into four quality grades: A B D and E.

There are 9 main classification societies in worldwide.
A.B.S    American Bureau of Shipping
B.V.     Bureau Veritas
C.C.S.   China Classification Society
D.N.V   Det Norske Veritas
G.L.    Germanischer Lloyd
K.R.    Korean Register of Shipping
L.R.    Lloyd’s Register of Shipping
N.K.    Nippon Kaiji Kyokai
R.I.N.A  Registro Italiano Navale
