NK Grade B Shipbuilding Steel Plate has the following advantages compared with other marine steel plates:

Good Toughness

 

During the voyage of a ship, it will be subjected to various external impacts, such as wave impacts and the movement of cargo. The good toughness of NK Grade B steel plates enables them to absorb and disperse these energies, reducing the risks of cracks and fractures in the steel plates, thereby ensuring the integrity and safety of the ship's structure.

 

High Strength

 

Its yield strength is not less than 235 MPa, and the tensile strength is between 400 MPa and 520 MPa. It can bear various loads under different working conditions of the ship, such as the weight of the ship's hull itself, the weight of the cargo, the weight of the equipment, and the hydrodynamic loads during navigation, providing reliable structural support for the ship.

 

Excellent Welding Performance

 

In the process of shipbuilding and ship repair, welding is the main method for connecting various components. NK Grade B steel plates have good welding performance, which can ensure the strength and sealing of the welded joints, reduce the occurrence of welding defects, improve the overall quality and reliability of the ship's structure, and also help to improve the construction efficiency and reduce costs.

 

Strong Corrosion Resistance

 

The seawater, salinity, humidity and other factors in the marine environment have strong corrosive effects on ship steel plates. Through reasonable chemical composition design and surface treatment, NK Grade B steel plates have good corrosion resistance and can be used for a long time in the harsh marine environment, effectively extending the service life of the ship and reducing maintenance costs.

Strict Quality Control

 

As a shipbuilding steel plate produced in accordance with the specifications of the Nippon Kaiji Kyokai, NK Grade B is subject to strict quality control and inspection during the production process to ensure that each steel plate meets the relevant standards and requirements. It has high quality stability and reliable performance, and can meet the high-quality requirements of shipbuilding and operation, providing a strong guarantee for the safe navigation of the ship.

 

Diverse Size Specifications

 

The thickness range of NK Grade B steel plates is from 4 mm to 260 mm, the width range is from 1200 mm to 4000 mm, and the length range is from 3000 mm to 18000 mm. Such diverse size specifications can meet the construction needs of different parts and structures of the ship, improve the applicability and utilization rate of materials, and reduce the processing allowance and waste.
