Product Description

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.
RINA A steel is a kind of hot rolled general tensile strength steel. General-strength RINA shipbuilding steel comes in 12 grades of 3 strengths,Grade A is one of the grades. Grade A steel plates have yield strength of 235 MPa, and ultimate tensile strength of 400-520 MPa. 

RINA is a founding member of the International Association of Classification Societies(IACS),formed in 1968. The RINA fleet is recognized by approximately 116 international flag authorities. RINA 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 A steel is the impact force subjected to 20 ° C
Grade B steel impact force at  0 ° C
Grade D steel impact force at -20 ° C
Grade E steel impact force at -40 ° C
