What are the materials of marine steel plates and their applications in shipbuilding?

Marine steel plate is a special steel plate material that is used exclusively for shipbuilding. As ships are used in the marine environment, they need to have good weather resistance, corrosion resistance and high strength, etc. Therefore, the material selection of marine steel plate and its application is crucial. In this paper, we will elaborate on the two aspects of the material of marine steel plate and its application in shipbuilding.

There are many kinds of materials of marine steel plate, and the common ones are common ship plate steel, light ship plate steel, high strength ship plate steel, etc. Among them, common ship plate steel is the most important one. Among them, ordinary plate steel is one of the most commonly used marine steel materials, its mechanical properties are better, with a certain degree of elasticity and toughness. Light ship plate steel is relatively light, the weight can not only reduce the hull load, but also improve the ship's cargo carrying capacity. High-strength ship plate steel, on the other hand, has excellent strength and toughness, which can make the hull more robust and durable.

In shipbuilding, marine steel plate is widely used. First of all, it is the inner and outer wall plate of the ship hull. As the main component material of the hull, marine steel plate is used to make the inner and outer wall plate of the hull, which can ensure the overall strength and stability of the hull. Secondly, it is the bottom plate and deck of the ship. Marine steel plate is used to make the bottom plate and deck of the hull, which can withstand the huge pressure from seawater and cargo to ensure the safe navigation of the ship. In addition, marine steel plate is also used in the ship's bulkheads and ship equipment support structure and other parts of the ship, play a load-bearing and support role.

The selection of marine steel plate material is related to different parts of shipbuilding and the use of the ship. For example, high yield strength ship plate steel is suitable for the main components of the ship's hull and high load-bearing parts, which can improve the strength and stability of the ship's hull. As for the parts with high demand for preventing corrosion and rust, such as the outer wall plate of the hull and the bottom plate of the ship, stainless steel plate with good corrosion resistance is usually chosen as the ship steel plate material. In addition, with the continuous development of shipbuilding technology, a new type of marine steel plate material has emerged, namely, composite ship plate steel. The material adopts multi-layer composite structure, which can meet the technical requirements of different parts and make the ship lighter and stronger.

To summarize, the material selection of marine steel plate and its application in shipbuilding are of great significance. There are many kinds of materials of marine steel plate, and different hull parts and applications need to choose different materials to ensure the safety and reliability of the ship. Marine steel plate is widely used in shipbuilding, covering key parts of the hull such as inner and outer wall plates, bottom plates and decks, which play the role of load-bearing and support. With the progress of shipbuilding technology, marine steel plate materials are also constantly innovating and developing, playing an important role in improving ship performance and safety.
