BV AH36 Shipbuilding steel plates are suitable for container and bulk cargo vessels as well as cruise ships, ferries and yachts.

AH36 steel plate is the grade of high-strength ship plate, and high-strength ship plate also has AH32.DH32, DH36, EH36 and so on. According to its different classification society certification, it can also be divided into LR, ABS, NK, DNV, CCS and so on. AH36 steel plate is mainly used to produce components with relatively large hull stress. The steel producers that can produce AH36 include Baosteel, Wuhan Iron and Steel, Shougang, Hunan Iron and Steel, Anshan Iron and Steel, Nangang, Xinyu and so on. The main factory form is the factory flat plate, with superior mechanical properties and precise dimensions. Common widths are 1800/2000/2200/2500MM.

Shipbuild plate refers to the hot-rolled steel plate used to manufacture the hull structure produced in accordance with the requirements of the classification society’s construction rules. The general-strength structural steels in the standards of China Classification Society are divided into four quality grades: A, B, D, and E (namely CCSA, CCSB, CCSD, CCSE); the high-strength structural steels in the standards of China Classification Society are three Intensity levels, four quality levels.

1. Commonly used ship plate steel models

1. AH32, AH36, DH32, DH36, etc.

These types of steel are code-approved ship plate steels and are commonly used in the shipbuilding industry. They are excellent in wear resistance, impact resistance and corrosion resistance, and are widely used in shipbuilding.

2. D36, E36, F36

These types of steels are also code-approved ship plate steels, but have higher strength and toughness than the AH series steels, making them suitable for marine engineering, ship structures and offshore installations.

3. HSLA series steel

HSLA is high-strength low-alloy steel, which has high strength, high plasticity and good welding performance. Commonly used HSLA series steels include: AH40, DH40, EH40 and FH40, etc. These steels are widely used in shipbuilding, marine engineering, port facilities and coastline construction due to their good corrosion resistance and long service life.

Second, the characteristics of ship plate steel

Ship plate steel needs to meet the following requirements:

1. Abrasion resistance: In seawater and humid environment, ship plate steel needs to have better wear resistance to increase the life of the hull.

2. Corrosion resistance: Due to the high content of salt, moisture and oxygen in seawater, ship plate steel needs to have excellent corrosion resistance to avoid rust and corrosion.

3. High plasticity: Ship plate steel needs to have good plasticity to facilitate steel processing and forming to meet different hull shape and size requirements.

4. Good welding performance: In the process of connecting and repairing ship plate steel, good welding performance is required to ensure the connection strength and the overall performance of the hull.

Ship plate is an important component in shipbuilding, and the selection of steel materials is very important. Commonly used ship plate steel models include AH32, AH36, DH32, DH36, D36, E36, F36 and HSLA series steel, etc. These steels have the characteristics of good wear resistance, good corrosion resistance, high plasticity and good welding performance, and are suitable for different fields such as shipbuilding, marine engineering and port facility construction.

The main difference between marine steel plates and ordinary steel plates lies in their use occasions and technical requirements.

First of all, marine steel plates are generally used in the construction and maintenance of boats. They need to have good corrosion resistance, compression resistance and low temperature toughness to ensure that ships can withstand extreme forces and environmental tests such as high pressure and large waves in harsh marine environments. Ordinary steel plates are mainly used in construction and engineering fields, and do not need to withstand the special requirements of the marine environment.

Secondly, the technical requirements for marine steel plates are more stringent than ordinary steel plates. For example, marine steel plates need to have high welding performance and low temperature toughness, and need to go through a series of production processes such as complex steel plate control, heating, rolling and cooling to ensure that their quality and performance meet the standards for ship construction and use. The production process of ordinary steel plates is relatively simple, and does not require too much processing and control.

To sum up, although both marine steel plates and ordinary steel plates are steel materials, there are obvious differences in their use occasions and production processes, and they need to be selected and purchased according to specific needs.
