AH Marine steel plate is a kind of high-strength, impact-resistant ship structure steel plate, with the following important parameters and production process:
1. Steel plate material: AH Marine steel plate usually uses ordinary carbon steel, low alloy steel or micro-alloy steel as the basic raw materials.
2. Strength grade: AH Marine steel plate is classified according to the different strength grades stipulated by the International Classification Society, such as AH32, AH36 and so on. These grades represent different minimum yield strength and tensile strength requirements.
3. Impact toughness: AH Marine steel plate needs to have good impact toughness to cope with the impact load in the complex environment at sea. Impact test is a common method to evaluate the impact toughness of steel plate.
4. Thickness and size: The thickness and size of the AH Marine steel plate are determined according to the classification society and design requirements, usually in the range of 5-100 mm.
5. Special treatment: In the production process, process measures such as controlling the rolling temperature and formula adjustment can be used to ensure that the composition uniformity and mechanical properties of the steel plate are met.
6. Testing and certification: strict quality control and testing is required in the production process, including chemical composition, mechanical properties, impact toughness and other aspects. Products need to meet the certification standards of international classification societies, such as China Classification Society (CCS), Norwegian Classification Society (DNV), Lloyd's Register (LR), etc.
7. Welding performance: AH Marine steel plates usually need to be welded, so welding performance is an important consideration, including welding plasticity, crack resistance, corrosion resistance and so on.
In general, the important parameters of AH Marine steel plate cover the material, strength grade, impact toughness, thickness and size, and the production process needs to follow the relevant process control and quality testing standards to ensure that the quality and performance of the product meet the requirements of the classification society.
