Ships or cargo ships

Steel is the most important material in shipbuilding or cargo ships, providing the structural integrity and durability required for marine vessels. The following is a detailed description of the types of steel used in shipbuilding and its components:

Types of steel used in shipbuilding:

1. Carbon Steel and Ductile Steel Grades: SS400 or LLOYD grade A

• Applications: These grades are used throughout the structure of the boat, forming the hull, decking, and almost everything that is in this area.
• Features: Suitable for marine engineering due to its high yield and tensile strength. Better fatigue resistance and low cost compared to wood or other materials.

2. High tensile steel class AH36, DH36, EH36:

• Applications: It is often used in the construction of hulls and main structures due to its higher strength. This allows for the use of thinner steel plates with lighter structures and good corrosion resistance.
• Features: These steels have high tensile strength and strength, and can be reached up to 220mm in thickness, providing them with a strong surface for marinability.

3. Stainless steel:

• Applications: Used for critical components those require corrosion resistance, such as propeller shafts. Deck equipment and areas exposed to salt water.
• Features: Contains chromium, which has excellent resistance to corrosion and staining

Vessel Components and Steel Applications

Hull:

• The hull is the main part of the boat, and it is typically constructed from carbon steel and ductile steel grades due to its strength and flexibility.
• The hull also uses high-tensile steel to reduce the overall weight of the boat without compromising its rigidity, such as ABS grade EH36.

Deck:

• The deck is the flat part of the boat used to install equipment and carry out various operations, usually made of carbon steel and ductile steel grades for durability, and high tensile steel is used to reduce the overall weight of the boat without compromising its rigidity.

Propeller shaft and fittings:

• Stainless steel is popular for propeller shafts and various deck equipment, because of its ability to resist corrosive marine environments.

Superstructure:

• The superstructure consists of a boat bridge. AH36, DH36 and ABS EH36 steels are used to provide high strength and corrosion resistance.

Conclusion:

The choice of steel for shipbuilding is determined by the specific needs of each part of the ship. Carbon steel and ductile or mild steel provide the integrity of the infrastructure. High-tensile steel provides strength with a lighter weight, and stainless steel provides corrosion resistance for critical components. The development of specialized steels such as AH36, DH36 and ABS EH36 has further improved the performance and safety of modern boats. Shipbuilding steel must meet strict standards to ensure the performance and safety of ships at sea. Innovations in steel production continue to improve the quality and ability of steel for shipbuilding.
