NV A550 Steel Plate Suppliers and Manufacturers

DNV-GL AH550/VL A550 shipbuilding steel plates are high-quality steel plates used in the construction of ships and offshore structures. DNV-GL AH550/VL A550 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.

VL A550 shipbuilding steel plates Heat Treatment Conditions

DNV-GL AH550/VL A550 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 AH550/VL A550 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 AH550/VL A550 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 AH550/VL A550 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.
