What‘s the feature of Gnee Ship Steel Plate?

SHIPBUILDING-STEEL-PLATE-FOR-SALE

Raw material selection: Gnee carefully selects high-quality raw materials for the production of shipbuilding steel plates. These materials are rigorously tested and inspected to ensure they meet the chemical composition, mechanical properties and other specifications required by international and national standards.

Manufacturing process: Gnee adopts advanced manufacturing process to produce shipbuilding steel plate. This includes precise control of the heating, rolling and cooling processes to achieve the desired mechanical properties and ensure uniformity across the sheet. Strict quality control measures are implemented at every stage of production to monitor and maintain the quality of the shipbuilding plate.

Testing and certification: Gnee conducts comprehensive testing and quality inspection of shipbuilding steel plates. This includes testing of mechanical properties such as tensile strength, yield strength and impact resistance, as well as dimensional inspection and non-destructive testing. Shipbuilding plates are certified by recognized classification societies such as ABS, DNV, LR, BV, ensuring compliance with international and national standards.

Documentation and Traceability: Gnee maintains detailed documentation and traceability records of each batch of shipbuilding steel plates. This includes material certificates, inspection reports and manufacturing records, enabling customers to verify the quality and compliance of the shipbuilding plate.

Continuous Improvement: Gnee is committed to continuous improvement of its manufacturing processes and quality management system. The company regularly reviews and updates its production procedures, equipment and quality control measures to improve the quality of shipbuilding steel plates and meet the changing requirements of international and national standards.

Tensile Strength: Gnee shipbuilding steel plate has high tensile strength, which can withstand greater tensile force without breaking or deforming. This makes the ship have better tensile performance when impacted by external forces, ensuring the structural safety of the hull.

Yield strength (yield strength): The yield strength of Gnee shipbuilding steel plate is also high, that is, it will not produce plastic deformation when subjected to a certain strain. This enables the ship to withstand high torsional and current pressures during operation, maintaining structural stability and integrity.

Impact Toughness: Gnee shipbuilding steel plate has good impact toughness, that is, it can not break when damaged and impacted. Critical to the safety of the ship in the event of a damaging collision or other unexpected impact, reducing the extent of structural damage.

Corrosion Resistance: Gnee shipbuilding steel plates are made of materials with good corrosion resistance, which can resist moisture corrosion and oxidation. This prolongs the life of the vessel and reduces maintenance costs.

Material selection: We choose materials with good corrosion resistance, such as stainless steel with high corrosion resistance, weathering steel, aluminum alloy, etc. These materials have a low oxidation rate and excellent element content, which can effectively resist oxidation, corrosion and other chemical reactions.

Coating: Gnee performs coating coating treatment for coatings used in shipbuilding, such as spraying or thermal bonding, etc. These coatings can form a protective film that effectively isolates the contact between the coating medium and the coating, reducing the possibility of corrosion.

Uniform thickness: The shipbuilding steel plate manufactured by Gnee has a thickness distribution, and precise control measures are taken during the manufacturing process to ensure that the thickness of the steel plate surface is uniform. This helps improve corrosion resistance and reduces the possibility of corrosion concentrations.

Resistance to marine chloride ions: Chloride ions in the marine environment are the main source of corrosion for shipbuilding steel plates. Gnee’s shipbuilding steel plate adopts the anti-chloride ion summary material and treatment process, which effectively reduces the corrosion degree of the steel plate after contact with seawater.

Anti-corrosion performance test: Gnee conducts corrosion resistance tests on shipbuilding steel plates, such as salt spray test, corrosion test, etc. These tests can simulate the corrosion situation in real marine environment, evaluate the corrosion resistance of the steel plate and ensure that it meets the relevant standards and regulations.

Cold Work Hardening: Gnee shipbuilding steel plate has high hardening during cold working, that is, its hardness and strength will gradually increase during the process of being processed. This is conducive to improving the deformation resistance, fatigue resistance and compression resistance of the steel plate, making it more suitable for bearing the load of the hull structure.

Processing Stability: Steel plates for shipbuilding have good stability during cold working, and are not prone to problems such as internal adhesion or cracking. This makes the manufacturing process more reliable, reducing scrap rates and the possibility of machining errors.

Cold Bending Properties: Gnee shipbuilding steel plates can be cold bent without breaking or cracking. This cold formability allows the steel plate to conform to the curved shape of the ship’s structure, providing better appearance and design flexibility.

Weldability: Gnee shipbuilding steel plate has good weldability and can be welded during cold working. This makes the manufacture of steel plates more convenient and enables the assembly and connection of complex structures.

Weldability: Gnee shipbuilding steel plate has good weldability and can be effectively joined with other metal materials. This means that during the welding process, the steel plate and the welding material can be well fused and form a firm weld, ensuring the strength and tightness of the welded joint.

Low tendency of welding hot cracking: Gnee shipbuilding steel plate has low tendency of hot cracking during welding. Hot cracking refers to the generation of cracks caused by thermal stress in the material during the welding process. The low thermal cracking tendency of Gnee shipbuilding steel plate can reduce defects and damages during welding, and improve the quality and reliability of welded joints.

High toughness: Gnee shipbuilding steel plate has high toughness, that is, it can resist the expansion of cracks during the welding process. This means that welded joints are less prone to cold cracks and hot cracks, thereby enhancing the durability and safety of welded joints.

Good welding deformation control: Gnee shipbuilding steel plate can control the amount of deformation in the welding process through appropriate welding process and parameters. This helps to keep the shape and dimension of the welded structure stable, reducing distortion and stress concentrations in the welded joint.

Gnee steel plate ship is relatively low in price while ensuring the quality, which can benefit from the following factors:

Production scale efficiency: Gnee steel plate shipbuilding is mass-produced on a large scale, which can reduce the production cost per unit product. Through mass production, fixed costs can be spread out and production efficiency can be increased, thereby reducing the production cost per ship.

Efficient production process: Gnee adopts advanced production process and equipment to make the production process more efficient. For example, using advanced CNC cutting technology, welding process and quality control system can reduce the scrap rate, reduce labor and material waste, and thus save costs.

Optimizing supply chain management: Gnee has established a solid supply chain management system and supplier network, and has established stable cooperative relationships with reliable raw material suppliers and parts suppliers. By optimizing the supply chain, obtaining more competitive raw material prices and more timely delivery, thereby reducing manufacturing costs.

Lean production concept: Gnee pays attention to lean production, and realizes cost reduction by eliminating waste and improving production efficiency. For example, measures such as reducing unnecessary inventory, improving line layout, implementing standardization and continuous improvement can increase production efficiency and save costs.

Innovative technology and engineering design: Gnee is committed to adopting innovative technology and engineering design to improve the performance and efficiency of ships. By using new materials, optimizing structural design, and improving ship energy utilization, the operating costs of ships can be reduced, and the price of ships can be reduced first.
