Cargo Shifting and Loading/Unloading: During cargo loading and unloading operations or when cargo shifts during a voyage, the ship's structure experiences additional loads. The elongation of the steel enables it to accommodate these changing loads. For example, in a bulk carrier, when the cargo is being loaded or unloaded unevenly, the steel structure can deform slightly without breaking, ensuring that the ship remains structurally sound and safe.

Long - Term Structural Integrity

Fatigue Resistance: Over the long - term operation of a ship, the structure is subjected to repeated loading and unloading cycles, which can lead to fatigue. The elongation property of LR/DH40 steel contributes to its fatigue resistance. When the steel can elongate and recover during these cycles, it is less likely to develop cracks due to fatigue. This helps to maintain the safety and performance of the ship over its service life, reducing the need for frequent and costly repairs.

Corrosion and Maintenance: The elongation property also affects the way the ship's structure responds to corrosion. If the steel has good elongation, it can better withstand the stresses caused by the loss of material due to corrosion. As corrosion occurs, the structure may experience local weakening, but the elongation ability allows the remaining sound steel to adjust and carry the load, delaying the onset of more severe structural problems and potentially reducing maintenance requirements.

 

 

 

Surface Treatment

Shot Blasting: Shot blasting is a common surface treatment method for LR/DH40 ship - building steel plate. High - speed projectiles are used to impact the surface of the steel plate, which can remove surface oxides, scale, and other impurities. This process also helps to improve the surface roughness of the steel, enhancing the adhesion of coatings such as paint or anti - corrosion coatings.

Pickling: Pickling is another surface treatment option. The steel plate is immersed in an acid solution to remove rust and other surface contaminants. This treatment is beneficial for preparing the steel surface for subsequent painting or other protective treatments to improve the corrosion resistance of the ship - building steel plate.
