RINA CCS Ah36 Shipbuilding Steel Plate

RINA CCS AH36 Shipbuilding Steel Plate is a high-strength structural steel plate used in shipbuilding. Here is a detailed introduction to it:

 

Classification Society Certification:

 

RINA: The Italian Classification Society (Registro Italiano Navale) is one of the full members of the International Association of Classification Societies (IACS). Established in 1968, it has rich experience and high authority in ship inspection, certification, and technical consulting. RINA's certification of ships and related materials has wide international recognition.

CCS: China Classification Society is a professional institution engaged in ship classification inspection services in China. It also has an important position and influence in the domestic and international shipbuilding industry. Ships and materials certified by CCS comply with the relevant specifications and standards of the China Classification Society, ensuring the quality and safety of ships.

 

Chemical Composition:

 

Carbon (C) content ≤ 0.18%. Controlling the carbon content helps ensure the welding performance and toughness of the steel plate.

Silicon (Si) content ≤ 0.50%. Silicon can increase the strength of the steel plate, but excessive silicon content will affect the toughness and welding performance of the steel plate.

Manganese (Mn) content is between 0.9 - 1.6%. Manganese is an important element to improve the strength and toughness of the steel plate.

Phosphorus (P) content ≤ 0.030%, and sulfur (S) content ≤ 0.030%. Low phosphorus and sulfur content can reduce the brittleness of the steel plate and improve the quality of the steel plate.

Acid-soluble aluminum (Als) content ≥ 0.015%. The addition of aluminum can refine the grains and improve the strength and toughness of the steel plate.

 

Mechanical Properties:

 

Yield strength: ≥ 355 MPa. Yield strength refers to the stress at which the material begins to undergo plastic deformation. A higher yield strength can ensure that the steel plate can withstand a larger load during use.

Tensile strength: 490 - 630 MPa. Tensile strength is the maximum stress that the material can withstand during the tensile process, reflecting the strength and toughness of the steel plate.

Elongation after fracture: ≥ 21%. Elongation after fracture is an index to measure the plasticity of the material. A higher elongation after fracture indicates that the steel plate has good plasticity and toughness and can undergo a certain deformation without easily breaking when subjected to external forces.

Impact toughness: According to different needs and usage environments, RINA CCS AH36 shipbuilding steel plates may need to meet certain impact toughness requirements. For example, steel plates used in low-temperature environments need to have good impact resistance to ensure the safety of ships.

 

Size Specifications:

 

Thickness: Generally 2 - 300 mm (commonly used thickness is 2 - 100 mm).

Width: 1000 - 3000 mm (commonly used width is 1000 - 2200 mm).

Length: Can be customized according to customer requirements, generally 1000 - 12000 mm.

 

 

 

 

The functions of certification by the China Classification Society (CCS) are as follows:

 

Ensuring quality and safety: CCS certification ensures that ships and related products meet high-quality and safety standards. It verifies that materials, components, and construction processes adhere to strict specifications to enhance the reliability and durability of ships.

Enhancing market competitiveness: For shipbuilders and operators, having CCS certification can increase market competitiveness. It demonstrates compliance with international and domestic regulations, giving customers confidence in the quality and safety of the vessels.

Facilitating international trade: CCS certification is recognized globally, facilitating international trade in the shipping industry. It allows ships to operate in different countries and regions, meeting the requirements of various maritime authorities.

Promoting technological innovation: The certification process encourages the adoption of advanced technologies and best practices in shipbuilding and marine engineering. It drives innovation to improve energy efficiency, environmental performance, and operational efficiency.

Providing technical support and expertise: CCS offers technical support and expertise throughout the certification process. This includes inspections, evaluations, and advice on design, construction, and maintenance, helping to ensure the long-term viability and safety of ships.
