ASTM A131/A131M
Marine structural steel profiles
Steel Grades: 普通强度: A, B, D, E; 高强度: AH32, DH32, EH32, AH36, DH36, EH36
Widely used in load-bearing and reinforcing components such as hull frames, deck beams, bulkhead stiffeners, and marine supports, various types of steel can be combined to form hull frames. Ordinary strength grades are used in standard areas, while high-strength grades are used in high-stress and weight-reduction zones. With its good weldability and low-temperature toughness, it is suitable for ship structural frames where welding assembly is the primary method and classification society require
DNV-OS-B101
DNV Marine Steel Specifications
Steel Grades: 普通强度: A, B, D, E; 高强度: AH32, DH32, EH32, AH36, DH36, EH36, AH40, DH40, EH40
Widely used in the hull frame, deck beams, bulkhead stiffeners of DNV-classed vessels, as well as load-bearing components such as offshore platform structures and marine engineering components. Standard strength grades are used in conventional areas, while high-strength grades are used in high-stress and weight-reduction zones. With good weldability and low-temperature toughness, it is suitable for cold-water environments and the skeletal structures of ships and marine equipment where welding is
ABS Rules Part 2
ABS marine steel specifications
Steel Grades: 普通强度: A, B, D, E; 高强度: AH32, DH32, EH32, AH36, DH36, EH36
Widely used in the hull structure framework, beams, columns, and stiffeners of ABS-classed vessels, various types of steel can be combined to form the hull frame. Ordinary strength grades are used in standard areas, while high-strength grades are used in high-stress and weight-reduction zones. With its good weldability and low-temperature toughness, it is suitable for ship hull structures primarily assembled by welding that meet classification society requirements.
EN 10225
Steel for marine structures
Steel Grades: S235G2, S275G2, S355G2, S355G3, S355G6, S355G8, S355G10, S420G2, S460G2
Widely used in load-bearing components such as offshore platform jackets, deck structures, wind turbine tower flanges, and marine engineering structures, various types of steel can be combined to form load-bearing frames. Grades are classified according to strength and delivery quality, allowing selection based on stress and marine environment. With excellent low-temperature toughness, weldability, and resistance to seawater corrosion, it is suitable for marine structures subjected to long-term
JIS G3106
Marine welded structural steel
Steel Grades: SM400A, SM400B, SM400C, SM490A, SM490B, SM490C, SM490YA, SM490YB, SM520B, SM520C, SM570
Widely used in welded load-bearing components such as the hull frame, deck beams, and bulkhead stiffeners of standard Japanese ships, various types of steel can be combined to form the hull frame. Grades are classified according to strength and impact toughness, allowing selection based on stress and operating temperature; Grade C offers better low-temperature performance. With its excellent weldability and strength-toughness combination, it is suitable for ship structural framework engineering
