Introduction to Shipbuilding Steel Plates

These are different grades of steel plates and sheets used in shipbuilding. Each grade is designed to meet specific requirements related to strength, toughness, and other mechanical properties to ensure the safety and durability of ships in harsh marine environments.

The abbreviations like ABS, Dnv, CCS, and Nk refer to different classification societies. ABS stands for the American Bureau of Shipping, Dnv is DNV GL (Det Norske Veritas Germanischer Lloyd), CCS is the China Classification Society, and Nk represents Nippon Kaiji Kyokai. These classification societies set standards and conduct inspections to certify that the steel meets the necessary quality and performance criteria for shipbuilding.

Grades and Their PropertiesAH36, AH32

Strength: AH36 has a higher strength than AH32. The yield strength of AH36 is typically around 355 MPa (minimum), while AH32 has a yield strength of around 315 MPa (minimum). These values ensure that the steel can withstand the loads and stresses imposed on the ship's structure during its operation, such as the weight of the cargo, waves, and other dynamic forces.

Toughness: They possess good toughness, which is crucial for withstanding impacts and preventing brittle fracture. The toughness of these steels allows the ship's structure to absorb energy during collisions or rough sea conditions.

Application: Commonly used in the construction of the hull, decks, and other load - bearing parts of ships. For example, AH36 is often used in areas that require higher strength, such as the bottom of the hull, where it needs to resist the pressure of water and the weight of the ship's contents.

 

 

 

 

Thickness	2-300mm (2-100mm usually used)
Width	1000-3000mm (1000-2200mm usually used)
Length	1000-12000mm or as your request

 

 

 

Classification Society Standards: The steel must meet the standards set by the respective classification societies. This involves inspections and tests at various stages of production. Tests may include tensile testing to determine strength, impact testing to evaluate toughness, and non - destructive testing to check for internal defects. For example, the ABS standards specify the acceptable range of mechanical properties and the procedures for quality control and certification.

Surface Quality and Finish: The surface of the steel plates should be free from significant defects such as cracks, laminations, and deep scratches. A smooth surface finish is often required, especially for parts that are exposed to the marine environment or are involved in welding operations. Good surface quality ensures proper adhesion of coatings and the integrity of welded joints.
