When ship plates with hardness such as ABS AH36, ABS DH36, ABS EH36, ABS FH36, Shipbuilding-Steel-Plate, and Offshore-Steel-Sheet are applied in shipbuilding, the following issues need to be noted:

 

Familiarize yourself with relevant shipbuilding standards and regulations to ensure that the selected steel plates meet the specific requirements for different types of ships and marine structures. For example, different classes of ships may have different requirements for the strength, toughness, and corrosion resistance of steel plates.

Pay attention to the certification and approval of steel plates by classification societies to ensure their quality and reliability.

Supplier selection：

Choose reliable steel plate suppliers with good reputations and quality assurance systems. Conduct thorough investigations on the supplier's production processes, quality control measures, and delivery capabilities.

Request samples and test reports to verify the quality and properties of the steel plates before making large-scale purchases.

Inspection and testing：

Implement strict inspection and testing procedures for incoming steel plates. This may include visual inspections for surface defects, dimensional checks, and mechanical property tests such as tensile strength, yield strength, and impact toughness.

Use reliable testing equipment and methods to ensure the accuracy and reliability of test results. Consider third-party inspection agencies for independent verification if necessary.

Welding considerations：

Understand the welding characteristics of the selected steel plates. Different grades of steel may require specific welding procedures and consumables. For example, some high-strength steels may require preheating and post-weld heat treatment to ensure weld quality and prevent cracking.

Select qualified welders and welding procedures that are compatible with the steel plates. Conduct welding process qualification tests to ensure that the welding quality meets the requirements.

Monitor the welding process closely to detect and address any welding defects promptly. Use non-destructive testing methods such as ultrasonic testing and radiographic testing to ensure the integrity of welds.

Cutting and forming：

Use appropriate cutting and forming methods to avoid damage to the steel plates. For example, plasma cutting or laser cutting may be suitable for precision cutting, while cold bending or hot forming may be used for shaping the plates.

Follow proper cutting and forming procedures to ensure dimensional accuracy and minimize residual stresses. Consider stress relief annealing if necessary to reduce the risk of distortion and cracking.

Surface treatment：

Apply appropriate surface treatment methods to protect the steel plates from corrosion. This may include painting, galvanizing, or using corrosion-resistant coatings.

Ensure that the surface treatment is carried out in accordance with the manufacturer's recommendations and relevant standards. Conduct regular inspections to monitor the condition of the surface treatment and address any issues promptly.
