CCS Grade D shipbuilding steel plate

CCS Grade D is a classification society standard for shipbuilding steel plate. It specifies the requirements for the mechanical properties, chemical composition, and other characteristics of the steel used in the construction of ships. Here are some key features of CCS Grade D shipbuilding steel plate:

Strength and Toughness: CCS Grade D steel plate has a minimum yield strength of 34,500 psi (235 MPa) and a minimum tensile strength of 58,000-75,500 psi (400-520 MPa). It offers good strength and toughness properties, ensuring the structural integrity of the ship.

Chemical Composition: The chemical composition of CCS Grade D steel typically includes elements such as carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), and trace amounts of other alloying elements. The exact composition may vary based on specific requirements and mill practices.

Weldability: CCS Grade D steel has good weldability, allowing for efficient fabrication and joining processes during ship construction.

Certification: Shipbuilding steel plates, including CCS Grade D, need to be certified by the China Classification Society (CCS) to ensure compliance with industry standards and regulations.

Applications: CCS Grade D steel plate is primarily used in the construction of ships and marine structures. It is suitable for various types of vessels, such as bulk carriers, container ships, tankers, and offshore platforms.

It's important to note that this information provides an overview of CCS Grade D shipbuilding steel plate. For detailed specifications and specific requirements, it is recommended to refer to the latest edition of CCS rules and consult with the shipyard or steel supplier.
