LR AH36 Structural Steel Plate 1500mm Width 6-650mm Thickness ASTM A131 Marine Grade
The LR AH36 Structural Steel Plate is manufactured under ASTM A131/A131M specifications, designed specifically for shipbuilding applications. These plates offer excellent impact strength and perform reliably across diverse marine environments. As a high-strength grade typically hot-rolled, they provide superior tensile strength and are available in multiple grades to meet various structural requirements.
Shipbuilding steel is categorized into standard strength and high strength grades. Standard strength includes quality grades A, B, C, and D, while high strength structural steel encompasses three strength levels across four quality grades.
- Standard Strength: A, B, D, E
- High Strength: AH32/36/40, DH32/36/40, EH32/36/40
High strength plates like AH36, DH36, and EH36 are particularly suited for high-stress areas of ships, offering equivalent strength with reduced thickness compared to general strength steel.
