Shipbuilding Steel Plate China Manufacturer
Marine steel plates are steel plates specially used for manufacturing hulls and other offshore structures. Since ships operate in marine environments, they need to withstand seawater corrosion, high-intensity pressure, and various harsh marine climate conditions, so marine steel plates must have excellent performance.
Marine steel plates can be divided into the following categories according to their mechanical properties and chemical composition:
Ordinary strength ship plates: such as A, B, D, and E grades, mainly used to manufacture hull structural parts.
High-strength ship plates: such as AH32, DH32, EH32, and FH32, have higher strength and are suitable for large ships and important structural parts.
Ultra-high strength ship plates: such as AH40, DH40, EH40, and FH40, are used for extra-large ships and ship structures in extreme environments.

High Strength
Marine steel plates need to have sufficient strength to ensure the safety and stability of the hull structure in the marine environment.
Corrosion Resistance
Due to long-term exposure to seawater, marine steel plates must have good corrosion resistance to prevent damage caused by seawater corrosion.
Welding Performance
Marine steel plates need good welding performance to ensure that welding operations can be carried out conveniently during the manufacturing process and that the welding parts have sufficient strength.
Impact Resistance
Marine steel plates need to have good impact resistance to cope with possible impacts and collisions in the marine environment.

Classification Societies That Certify Shipbuilding Steel Plate
Classification societies are organizations that formulate, certify, inspect and issue certificates for ship and marine engineering structures. Here are some of the major internationally renowned classification societies:
1. American Bureau of Shipping (ABS)
2. Det Norske Veritas Germanischer Lloyd (DNV GL)
3. Bureau Veritas (BV)
4. Lloyd’s Register of Shipping (LR)
5. Registro Italiano Navale (RINA)
6. China Classification Society (CCS)
7. Nippon Kaiji Kyokai (NK)
8. Korean Register of Shipping (KR)
9. Indian Register of Shipping (IRS)
10. Russian Maritime Register of Shipping (RS)
These classification societies play a vital role in the global shipping and offshore engineering fields by formulating and implementing technical standards to ensure the safety, environmental protection and performance reliability of ships and offshore engineering structures.
Shipbuilding Steel Plate Production Process
The manufacturing process of marine steel plates includes the following main steps:
Smelting: The converter or electric furnace steelmaking process is used to ensure the purity and uniformity of the molten steel.
Rolling: The steel ingot is rolled into a steel plate of the required thickness through the hot rolling process.
Heat treatment: The steel plate is subjected to heat treatment processes such as normalizing and tempering to improve the mechanical properties of the steel plate.
Inspection: The finished steel plate is subjected to strict mechanical properties, chemical composition and non-destructive testing to ensure that it meets the standards and requirements of the classification society.
