DNV-GL, VL FH620 and DNV-GL, VL F620 are high-strength shipbuilding steel plates that are specifically designed to meet the rigorous standards set by the Det Norske Veritas (DNV) and Germanischer Lloyd (GL) classification societies. These steel grades are widely used in the construction of ships and offshore structures due to their excellent mechanical properties and resistance to corrosion and fatigue.

The chemical composition of DNV-GL, VL FH620 and VL F620 steel plates is carefully controlled to ensure optimal performance. They typically contain carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, copper, and other alloying elements in specific proportions. This composition allows for excellent strength, toughness, and weldability, which are crucial for shipbuilding applications.

In terms of mechanical properties, these steel plates possess high yield strength and tensile strength, making them suitable for withstanding the loads and stresses encountered in marine environments. They also exhibit good ductility and impact resistance, ensuring that the structures they are used in can absorb and distribute energy effectively during impact events.

The heat treatment state of DNV-GL, VL FH620 and VL F620 steel plates is typically normalized or quenched and tempered, depending on the specific requirements of the application. Normalized steel has improved toughness and weldability, while quenched and tempered steel offers higher strength and resistance to fatigue and corrosion.

The steel plates are available in a range of thicknesses and widths, allowing for flexibility in design and construction. The typical thickness range can vary from several millimeters to over a hundred millimeters, depending on the specific grade and application.

Impact tests are conducted on DNV-GL, VL FH620 and VL F620 steel plates to assess their ability to withstand low-temperature conditions. These tests ensure that the steel maintains its mechanical properties even at extremely cold temperatures, making it suitable for use in Arctic and other cold environments.

The main application scenarios for these steel plates include the construction of ships, offshore platforms, and other marine structures. Their high strength and corrosion resistance make them ideal for use in hulls, decks, and other critical components that require durability and reliability.
