Shipbuilding steel is an indispensable material in the marine industry. With strict standards, steel types such as AH36, DH36, EH36 are commonly used thanks to their physical and mechanical properties and high bearing capacity. Below are the important characteristics of each type of steel.
1. Technical Properties of AH36 Steel
AH36 steel is a high-strength steel commonly used in ship deck structures and hulls.
1.1. Weldability, Tensile Strength, and Yield Strength
-
Weldability: Easy to weld and process, suitable for shipbuilding structures requiring flexibility.
-
Tensile strength: 490 – 620 MPa.
-
Yield strength: ≥ 355 MPa.
1.2. Applications of AH36 Steel
-
Used in deck structures of ships.
-
Applied in hulls, ship floors, and moderately stressed components.
2. Technical Properties of DH36 Steel
DH36 steel has higher strength than AH36 and is commonly used in high-stress structural components.
2.1. Weldability, Tensile Strength, and Yield Strength
-
Weldability: Good weldability, but requires temperature control to ensure weld quality.
-
Tensile strength: 490 – 620 MPa.
-
Yield strength: ≥ 355 MPa.
2.2. Applications of DH36 Steel
-
Used in ship hulls, ship bodies, and load-bearing structures.
-
Applied in marine structures requiring high durability.
3. Technical Properties of EH36 Steel
EH36 is the strongest steel in this group, suitable for harsh environmental conditions.
3.1. Weldability, Tensile Strength, and Yield Strength
-
Weldability: More challenging to weld than AH36 and DH36, requiring specialized welding techniques.
-
Tensile strength: 490 – 620 MPa.
-
Yield strength: ≥ 355 MPa.
3.2. Applications of EH36 Steel
-
Used in underwater load-bearing components.
-
Applied in ship structures operating in extreme weather conditions.
4. Conclusion
Choosing the appropriate steel type depends on technical requirements and usage conditions:
-
AH36 is suitable for deck structures.
-
DH36 is used for ship hulls and high-load components.
-
EH36 is ideal for extreme marine environments.
