Steel Plate For Shipyard

Steel plates for shipyards have the following characteristics and considerations:

 

Mechanical Properties

 

Strength Requirements

Yield Strength: Different areas of a ship require steel plates with varying yield strengths. For example, the hull bottom, which experiences high hydrostatic pressure, may need steel plates with a yield strength of 355 MPa or higher (such as in AH36 or DH36 grades) to withstand the compressive forces. The deck and superstructure can use plates with slightly lower yield strengths, depending on the design load.

Tensile Strength: Tensile strength is crucial for withstanding the pulling forces that occur during ship operations. A typical tensile strength range for shipyard steel plates is between 400 - 630 MPa, ensuring the material can resist breaking under tension.

Toughness and Impact Resistance

Low - Temperature Toughness: Ships operating in cold waters demand steel plates with good low - temperature toughness. For instance, at - 40°C, the impact energy of the steel should be sufficient to prevent brittle fracture. This is especially important for the bow and stern regions, which are more exposed to cold air and water impact.

Impact Resistance in General: Steel plates need to be able to absorb the energy from impacts, such as during docking or collisions with floating debris. The impact resistance is measured by conducting impact tests, and the required values depend on the ship's size and operating conditions.

Material Grades and Classifications

 

Common Grades: Some of the common grades used in shipyards are AH32, AH36, DH32, and DH36. These grades are defined by international standards and have specific mechanical property requirements. For example, AH36 steel has a minimum yield strength of 355 MPa and a tensile strength in the range of 490 - 620 MPa.

Classification Society Approvals: Steel plates must be approved by classification societies such as Lloyd's Register (LR), American Bureau of Shipping (ABS), or Bureau Veritas (BV). These societies set strict guidelines for the quality and performance of the steel. The approval process involves testing the material at various stages of production and ensuring compliance with their standards.
