BV D shipbuilding steel is a type of structural steel standardized by the Bureau Veritas for shipbuilding. It has the following characteristics and application scope:
Characteristics
Good Toughness: BV D Shipbuilding Steel has excellent toughness, especially at low temperatures. It can effectively absorb energy when the ship is subjected to external forces such as waves and impacts, preventing brittle fracture and ensuring the safety of the ship's structure. This is of great significance for ships sailing in cold regions or in harsh sea conditions.
High Strength: It has a yield strength of 235MPa and a tensile strength in the range of 400 - 520MPa. It can withstand the various loads that a ship encounters during navigation, including the weight of the ship's hull, cargo, and the pressure generated by seawater, ensuring the stability of the ship's structure.
Excellent Weldability: This steel is easy to weld and can meet the complex welding process requirements in ship construction. Appropriate welding processes can ensure the quality of welded joints, making the performance of the welded parts close to that of the base metal, thus ensuring the integrity of the entire ship's structure.
Good Corrosion Resistance: BV D Shipbuilding Steel has a certain degree of resistance to seawater corrosion. It can resist the chemical and electrochemical corrosion of seawater to a certain extent, and also has a certain resistance to some chemical substances in the marine environment, which helps to extend the service life of the ship.
Application Scope
Ship Hull Structure: It is widely used in the construction of various ship hulls, such as cargo ships, passenger ships, tankers, and container ships. Whether it is the ship's outer shell, deck, or internal skeleton structure, BV D Shipbuilding Steel can be used to ensure the strength and stability of the hull. It is especially suitable for the construction of small and medium - sized ships.
Marine Engineering Structures: In the field of marine engineering, it is used in the construction of key parts of offshore drilling platforms, such as support frames and platform decks. It can withstand the huge loads and complex stresses in the marine environment, ensuring the safe operation of the platform.
Ship Repair and Reconstruction: In the process of ship repair and reconstruction, BV D Shipbuilding Steel can be used to replace damaged or aged hull components, restore the structural strength and performance of the ship. At the same time, when upgrading and reconstructing the ship, this steel can also be used to strengthen the hull structure to meet new usage requirements.
