The selection principle of AH marine steel plate mainly includes the following points:
1. Strength and toughness: AH marine steel plate needs to have enough strength and toughness to withstand the various loads and environmental conditions that the ship may encounter during operation at sea.
2. Corrosion resistance: AH marine steel plate should choose a material with good corrosion resistance, because the ship is vulnerable to corrosion of corrosive media such as salt water and moisture in the marine environment.
3. Weldability: AH marine steel plate needs to have good weldability in order to carry out the structural connection and repair of the ship.
4. Low temperature toughness: When the ship operates in an extremely cold marine environment, the material should have good low temperature toughness to avoid brittle fracture.
5. Cost effectiveness: under the premise of meeting the ship design and safety requirements, the selection of economical and practical materials to ensure the cost control of the project.
Construction proposals include:
1. Comply with relevant standards: When selecting and using AH marine steel plate, the provisions of international classification societies or relevant standards should be followed to ensure that the quality and performance of materials meet the requirements.
2. Correct steel plate storage and treatment: For AH marine steel plates, they should be properly stored and prevented from being eroded by moisture and corrosive media. In the construction process, the steel plate should be correctly handled to avoid scratches, deformation and other problems.
3. Ensure the quality of welding: For the parts that need to be welded, appropriate welding methods and processes should be taken to ensure the quality and reliability of the weld.
4. Regular inspection and maintenance: After the operation of the ship, the status of the AH marine steel plate should be regularly checked, and any possible damage or corrosion problems should be discovered and repaired in time to maintain the integrity and safety of the hull.
Please note that specific material selection principles and construction recommendations may vary depending on vessel type, design requirements and application environment. It is recommended that you refer to the relevant professional guidance and standards in practical application.
