CCS Grade C Shipbuilding Steel Sheet

CCS Grade D shipbuilding steel plate is mainly used to build vessels and ships which are sailing in cold ocean waters belows minus 20 centigree.

GNEE steel foucs on rolling wide heavy shipbuilding plate,up to today,we can roll the maximum thickness for shipbuilding plate CCS Grade D shall be 300mm,and the maximum width shall be till 4200mm.

For the thickness above 40mm,our engineers suggest customers accept doing Normalized heat treatment for CCS Grade D steel plates.

CCS marine steel sheet product details

CCS grade D marine steel plate refers to a specific type of steel plate that meets the classification requirements of the China Classification Society (CCS) for use in marine applications, specifically for grade D. CCS is a recognized classification society responsible for setting standards and rules for ships and offshore structures in China.

The CCS grade D marine steel plate is typically used in the construction of ship hulls and other marine structures. It possesses good strength and toughness properties, making it suitable for withstanding the harsh conditions encountered at sea. The steel plate is manufactured according to specific requirements set by CCS, ensuring compliance with industry regulations and safety standards.

The grade D designation indicates the level of tensile strength and impact toughness the steel plate possesses. It signifies that the material has a minimum yield strength of 235 MPa (megapascals) and a minimum tensile strength of 400-520 MPa. These mechanical properties make CCS grade D marine steel plates suitable for various structural components of ships and offshore platforms.

In addition to its mechanical properties, CCS grade D marine steel plate undergoes rigorous testing and inspection procedures to ensure quality and adherence to classification society standards. This includes dimensional checks, visual inspections, ultrasonic examinations, and mechanical property tests.

When selecting CCS grade D marine steel plates, it is crucial to consider factors such as plate thickness, width, length, and any additional requirements specified for a particular project or application.

Overall, CCS grade D marine steel plates provide reliable and durable solutions for marine construction projects, meeting the stringent requirements set by the China Classification Society for safe and efficient operations at sea.

CCS shipbuilding steel plates are generally classified into four grades: A, B, D, and E. These grades have different minimum yield and tensile strengths and are categorized according to their chemical composition and mechanical properties. CCS Grade A and CCS Grade B have a minimum yield strength of 235 MPa (34,000 psi) and a minimum tensile strength of 400-520 MPa (58,000-75,000 psi). 75,000 psi), while CCS Class D and CCS Class E have a minimum yield strength of 275 MPa (40,000 psi) and a minimum tensile strength of 440-570 MPa (64,000-83,000 psi).
