Description
|
Key Differences
|
AH36
|
High-strength, low-alloy structural steel
|
Offers excellent corrosion resistance and weldability. Suitable for shipbuilding and offshore structures.
|
DH36
|
High-strength, low-alloy structural steel
|
Provides good toughness properties and higher strength compared to AH36. Used in shipbuilding and offshore applications.
|
EH36
|
High-strength, low-alloy structural steel
|
Exhibits superior toughness and impact resistance. Ideal for demanding marine and offshore environments.
|
FH36
|
High-strength, low-alloy structural steel
|
Offers high tensile strength and improved corrosion resistance. Employed in shipbuilding and offshore platforms.
|
AH40
|
High-strength, low-alloy structural steel
|
Designed for use in the construction of ships' hulls. Provides excellent weldability and impact toughness.
|
DH40
|
High-strength, low-alloy structural steel
|
Exhibits good fatigue resistance and high strength. Suitable for shipbuilding applications where low-temperature toughness is required.
|
EH40
|
High-strength, low-alloy structural steel
|
Shows excellent weldability, impact toughness, and resistance to brittle fracture. Used in marine engineering and offshore structures.
