ASTM A131 EH40 Shipbuilding and Offshore Platform Steel

ASTM A131 EH40 steel Description

EH40 Shipbuilding and Offshore Platform Steel is a common high-strength, low-alloy steel plate. Its strength is several times higher than that of ordinary steel plates. It can increase the load capacity of ships to a certain extent and reduce the weight of the hull at the same time. EH40 high-strength steel plates are mainly used in hulls, bridges, and ship components in the shipbuilding industry. EH40 shipbuilding steel plate has the advantages of good corrosion resistance and good weldability. It can be welded by various welding methods, which facilitates processing and repair during the manufacturing process, and improves the reliability and maintainability of the ship. ASTM A131 EH40 high-strength steel is widely used in the shipbuilding industry.

EH40 high-strength steel plate has excellent corrosion resistance. Working in the marine environment, it will be corroded by seawater, sea salt, sea fog and other environments. EH40 steel plate can effectively prolong the service life of the ship. In addition, the EH40 high-strength steel plate also has excellent wear resistance and impact resistance, which can effectively protect the hull structure.

The tensile strength of EH40 marine steel plate/coil has reached 390~510MPa, which is several times higher than that of ordinary steel plates, which can improve the bearing capacity of the hull and reduce the weight of the hull at the same time. In the case of the same load capacity, the use of EH40 high-strength steel plates can reduce the weight of the hull, thereby improving the speed and economy of the ship.
