RINA Marine Steel Plate DH40.
The international standards for the chemical composition of shipbuilding steel plates are mainly reflected in the specification requirements of various classification societies. The following are some common international standards:
American Bureau of Shipping (ABS): There are clear regulations on the chemical composition of shipbuilding steel plates of different strengths and grades. For example, for high-strength steel FH32, the carbon content C is ≤0.18%, the silicon content Si is ≤0.50%, the manganese content Mn is 0.90 - 1.60%, the phosphorus content P is ≤0.035%, the sulfur content S is ≤0.035%, and the aluminum content Al is ≥0.015%.
Bureau Veritas (BV): It stipulates that the chemical composition of shipbuilding steel plates must meet specific ranges and proportions. Taking a certain type of ship plate as an example, there is an upper limit requirement for carbon content, and the contents of elements such as silicon and manganese are also within a certain range. At the same time, the content of impurity elements such as phosphorus and sulfur is strictly limited to ensure the quality and performance of the steel plate.
Lloyd's Register (LR): There are detailed standards in terms of chemical composition. For general-strength ship plates, the contents of elements such as carbon, silicon, and manganese need to comply with the regulations of corresponding grades, and the contents of phosphorus and sulfur are controlled at a low level to ensure that the welding performance and toughness of the steel plate meet the requirements of shipbuilding.
| Classification Society | General Strength Structural Steel | High Strength Structural Steel |
|---|---|---|
| CCS | Divided into four quality grades: A, B, D, and E | Three strength levels and four quality grades (such as AH32, DH32, EH32, AH36, DH36, EH36, AH40, DH40, EH40, etc.) |
| ABS | The division of general strength structural steel may be similar, but the specific requirements may be different | The strength level and quality grade division of high-strength structural steel are similar to CCS, but the specific numerical requirements may be different. |
| DNV | The quality grade division of general strength structural steel may be similar | The relevant regulations of high-strength structural steel may be different from other classification societies in terms of strength level and quality grade. |
| BV | General strength structural steel has four quality grades: A, B, D, and E; high-strength structural steel is divided into four quality grades: A, D, E, and F, and three strength levels (32, 36, 40). | / |
| LR | The grade division of general strength structural steel and high-strength structural steel needs to refer to specific specifications. | / |
| GL | The quality grade division of general strength structural steel may be similar | The specific regulations of high-strength structural steel may be different from other classification societies. |
| RINA | The grade division of general strength structural steel and high-strength structural steel needs to refer to specific specifications. | / |
| KR | The grade division of general strength structural steel and high-strength structural steel needs to refer to specific specifications. | / |
