LR/EH32 Ship Building Plate

 

The implementation standards of shipbuilding steel plate LR/EH32 are mainly reflected in the following aspects:

 

Chemical composition standards:

 

Carbon (C) content is usually required to be no higher than 0.18%.

Manganese (Mn) content is between 0.90%-1.60%.

Silicon (Si) content is 0.10%-0.50%.

Phosphorus (P) content is not more than 0.04%.

Sulfur (S) content is not more than 0.04%.

It may also contain some trace alloy elements. For example, the aluminum (Al) content is required to be not less than 0.015%. The content control of these elements is very important for ensuring the performance and quality of the steel plate.

 

 

 

Size and tolerance standards:

 

Thickness tolerance: The thickness of the steel plate should be kept uniform within the specified range. For LR/EH32 shipbuilding steel plates of different thicknesses, there are corresponding standard requirements for thickness tolerance to ensure the strength and stability of the steel plate during use.

Width and length tolerance: The width and length also need to meet the design requirements, and the tolerance is controlled within a small range to avoid problems such as loose splicing and size mismatch during ship construction.

Flaw detection standards:
Generally, flaw detection tests such as ultrasonic flaw detection and radiographic flaw detection are required to detect whether there are cracks, slag inclusions and other defects inside the steel plate. The flaw detection level and detection method should comply with relevant standards and specifications.

 

Certification standards:
The certification of Lloyd's Register of Shipping (LR) can be implemented to meet its various requirements for shipbuilding steel plates to ensure the quality and reliability of the steel plates, and it is applicable to fields such as shipbuilding and marine engineering.

 

In short, the implementation standards of shipbuilding steel plate LR/EH32 are multi-faceted, involving chemical composition, mechanical properties, size tolerance, surface quality, flaw detection and many other links. The strict implementation of these standards is crucial for ensuring the safety and reliability of ships. The specific standard values may vary slightly according to different classification society certifications, manufacturers and usage requirements.
