Product Standards: DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates comply with the standards of Det Norske Veritas (DNV) and Lloyd's Register of Shipping (LR). These standards ensure that the steel plates meet the requirements of shipbuilding and offshore engineering.

 

Chemical Composition: The chemical composition of DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), nickel (Ni), chromium (Cr), molybdenum (Mo), and vanadium (V). The specific composition varies depending on the standard requirements, but generally contains a small amount of alloy elements to improve the strength and corrosion resistance of the steel plates.

 

Mechanical Properties: The mechanical properties of DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates include tensile strength, yield strength, elongation, and impact energy. These properties ensure that the steel plates have sufficient strength and ductility to withstand the loads and stresses encountered in shipbuilding and offshore engineering.

 

Heat Treatment Conditions: DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates can be heat-treated by quenching and tempering or normalizing. Quenching and tempering treatment can improve the strength and hardness of the steel plates, while normalizing treatment can improve the ductility and toughness of the steel plates.

 

Low-Temperature Impact Test: DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates must undergo low-temperature impact testing to ensure their performance at low temperatures. The impact energy and brittle transition temperature are important parameters to evaluate the low-temperature toughness of the steel plates.

 

Dimensions: The dimensions of DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates range from 2mm to 100mm in thickness and from 1000mm to 3000mm in width. The length can be customized according to customer requirements.

 

Main Applications: DNV-GL A/VL Grade A/DNV-GL GrA shipbuilding steel plates are widely used in the construction of ships, offshore platforms, bridges, and other structures. They are suitable for use in harsh marine environments due to their excellent corrosion resistance and strength.
