A460 DNV High-Strength Structural Steel for Container Ships - Knowledge

DNV Grade A460 shipbuilding steel plate is an extra high-strength steel certified by DNV (Det Norske Veritas) for use in shipbuilding and offshore structures. It has a minimum yield strength of 460MPa and is known for its high tensile strength, toughness, and impact resistance. This type of steel is designed to meet rigorous maritime standards and is typically manufactured through processes like quenching and tempering to ensure its mechanical properties.

DNV Grade A460 Shipbuilding Steel Plate Application

DNV Grade A460 Marine Steel Plate Shipbuilding

Large Bulk Carriers / Oil Tankers

Suitable for deck longitudinal frames, side shell plates of Cape - size bulk carriers, and structural components in the cargo hold area of VLCCs (Very Large Crude Carriers). For example, when DNV Grade A460 Marine Steel Plate is used for the deck web beams of a 200,000 DWT bulk carrier, the plate thickness can be reduced by 15% while meeting the structural strength requirements under heavy - load conditions.

Container Ships

Used for hatch coamings and top web beams of ultra - large container ships with over 18,000 TEUs. DNV Grade A460 ship plate can handle the concentrated loads from stacked containers and wave impacts.

Offshore Engineering Equipment

FPSO (Floating Production, Storage and Offloading Unit)

Applied to module support structures and mooring system connectors, withstanding alternating loads and corrosion in the marine environment. For example, in an FPSO project in Brazilian oil fields, DNV Grade A460 Shipbuilding Steel Plate is used for the main beam structures of key load - bearing modules.

Offshore Wind Turbine Jacket

As a lower support structural component of offshore wind platforms, DNV Grade A460 Offshore platform Steel plate can withstand long - term fatigue loads from sea winds and waves, and also has durability in the marine atmospheric corrosion environment.

DNV Grade A460 Marine Steel Plate Special Vessels and Structures

LNG Carriers (Partial Areas)

Used for superstructure structures and mooring equipment bases in non - low - temperature areas. While meeting strength requirements, DNV Grade A460 ocean steel is compatible with efficient welding processes to shorten the construction period.

Ocean Fishing Processing Vessels

Suitable for heavy equipment bases and refrigerated hold support structures. DNV Grade A460 Shipbuilding and Offshore platform Steel plate can handle equipment vibration and low - temperature conditions (refrigerated environment).
