In the complex engineering of shipbuilding, the correct selection of shipbuilding steel is a key link in laying the foundation for ship quality.
First, it is necessary to clarify the use scenario and strength requirements of the ship. If the ship mainly sails on ocean routes with strong winds and waves and frequently encounters strong winds and huge waves, it is necessary to use high-strength shipbuilding steel. This type of shipbuilding steel can withstand huge external impacts, ensure that the hull maintains a stable structure under harsh sea conditions, reduce the risk of damage to the hull due to inability to withstand pressure, and ensure the safe navigation of the ship.
Secondly, we must focus on the toughness of shipbuilding steel. For ships that need to operate in cold waters, such as those sailing in the Arctic route, toughness in low temperature environments is crucial. At this time, shipbuilding steel that can still maintain good toughness under low temperature conditions should be selected to avoid brittle fracture of the hull and ensure that the ship can operate normally under extremely cold conditions.
Furthermore, corrosion resistance is a factor that cannot be ignored in the selection of shipbuilding steel. Since ships are in contact with seawater for a long time, the strong corrosiveness of seawater is a severe test for the hull. If the ship will sail in a sea with high salinity and strong corrosion, it is necessary to choose shipbuilding steel with excellent corrosion resistance. Shipbuilding steel with special alloy formula and treatment process can effectively resist seawater erosion, extend the service life of the ship and reduce maintenance costs.
In addition, the processing performance of shipbuilding steel should not be ignored. According to the process and design requirements of shipbuilding, shipbuilding steel that is easy to process and shape should be selected to ensure smooth processing during cutting, welding and other processing, and ensure the quality and integrity of the hull structure.
Finally, consider the cost reasonably. On the premise of meeting the various performance requirements of the ship, comprehensively evaluate the prices of different shipbuilding steels, select products with high cost performance, and maximize economic benefits while ensuring the quality of the ship.
