The improvement of ABS EH40 marine steel plate process and performance

The production process improvement and performance improvement of ABS EH40 marine steel plate can be discussed from the following aspects:

1. Improve the precision of chemical composition, ensure that the content of alloying elements meet the standard requirements, reduce the content of sulfur, phosphorus and other elements, so as to improve the corrosion resistance of ABS EH40 marine steel plate.

2. Microalloying technology is introduced to refine steel grains by controlling heating temperature, holding time and other parameters, so as to improve the strength and toughness of ABS EH40 marine steel plate.

3. Optimized rolling process and adopted controlled rolling and isothermal rolling technology to improve the yield and dimensional accuracy of ABS EH40 marine steel plate, as well as improve the structure and properties of steel.

4. Strengthen cooling control, avoid excessive precipitation, annealing softening and other phenomena of steel, so as to ensure the tensile strength and toughness of ABS EH40 marine steel plate.

5. Strengthen defect control, produce in strict accordance with the established quality management system, control the quantity and size of the surface and internal defects of steel, so as to avoid affecting the performance of ABS EH40 marine steel plate.

Through the above process improvement measures, the performance and quality of ABS EH40 marine steel plate can be improved to meet the needs of different fields, but also conducive to promoting the development of domestic Marine steel.
